The chemical elements covered here are tricky. You have been warned! This quick chemistry quiz is all about matching periodic table elements with their proper groups. The touchy stuff involves deciphering multiple names for individual groups. Science know-it-alls know there are more and less modern naming conventions out there for periodic elements and their categories. Stick with the more modern group names and their respective group numbers and you'll ace these solids, liquids and gases with few-to-no difficulties.
Coinage metals, copper family and group are group 11 elements that inhabit periods 4 through 7. Alkali metals, lithium family and group are group 1 elements that span periods 2 through 7. Peer at your periodic table long enough and you'll start to see the grouping patterns of these elements illumine. It also helps if you're a chemistry whiz who knows how to group elements based on atomic numbers and all that technical stuff. The makers of those easy-to-read, color-coded periodic tables made things so much easier for the rest of us less-adept-at-tech folks who are no less intrigued by science.
So whatever your level of science mastery, give this quiz a shot! Scroll on to put those atomic numbers in their places.
Cadmium's atomic number is 48. As with other elements in the zinc group, cadmium has a valence electron count of 2.
Group 7 includes the elements manganese, technetium and bohrium as well as rhenium which are transition metals. Manganese is the most common element in the group.
The helium or neon family is group 18 in the periodic table. Elements in this group are referred to as noble gases or inert gases.
"Triels" is another name for elements in group 13, or the boron group, of the periodic table. This group contains elements such as boron, gallium and aluminium (or aluminum).
The symbol Cr stands for the element chromium, which belongs to group 6 in the periodic table. Elements in this group possess either one or two valence electrons. Tungsten is another member of this element group.
The vanadium group is group 5 in the periodic table. Elements of this group are transition metals with a valence electron count of 2. Niobium is the only member with a valence electron count of 1.
Rhodium has an atomic number of 45 and the element contains 1 valence electron, whereas other elements in the cobalt group have a valence electron count of 2. Rhodium is an extremely rare element that exists in 4.6 percent of the native platinum metal compounds.
The International Union of Pure and Applied Chemistry, or IUPAC, standardized modern naming conventions for previously inconsistent designations in the periodic table. The IUPAC group 8 is the iron group or iron family, which includes the transition metals ruthenium, iron, osmium and hassium.
D-block elements, also known as transition elements, have valence electrons in two shells instead of just one. Valence electrons enable the formation of chemical bonds. The titanium group is group 4 of the periodic table and includes hafnium, rutherfordium, zirconium and titanium.
Lanthanides are 15 consecutive metals in the periodic table that are often called rare-earth elements. Typical valences are 3 and 4, and atomic numbers range from 57 to 71. Silver has an atomic number of 47.
Calcium is the fifth most abundant element in the Earth's crust. Other alkaline-earth metals include beryllium, radium, barium, magnesium and strontium.
Plutonium has atomic number 94, which is within the range of elements, of atomic numbers 89 to 103, that include the actinide or actinoid elements. Actinide elements share radioactive traits.
Scandium is a rare-earth metal that belongs to group 3 in the periodic table. Scandium is a reactive metal with 2 valence electrons.
Group 11 in the periodic table contains the coinage metals that include copper, silver and gold. These elements all have a valence of 1 electron.
Hydrogen has atomic number 1 and is the lightest of the elements. Hydrogen is a reactive nonmetal and is one of two period 1 elements; Helium is the other.
Group 14 of the periodic table includes carbon, silicon, germanium, tin, lead and flerovium. Tetrels, from "tetra" which is the Greek for four, is another word for group 14 elements. Elements in this group have a valence of 4.
Pnictogens, or pentels, are group 15 elements in the periodic table. Arsenic, as with the other congeners of this group, has 5 valence electrons.
Chalcogens are also called the oxygen family or group 16 elements of the periodic table. Sulfur is the period 3 element with atomic number 16 in the chalcogen group.
Cesium has the symbol Cs and is a group 1 alkali metal in the periodic table. Cesium is one of the softest metals, and it is highly reactive.
Silicon is the second element in the carbon group, which is also group 14 of the periodic table. Coinage metals are group 11 elements. A group in the periodic table is also described as a "family."
Strontium is an alkaline-earth metal within the period 5 elements of the periodic table. This element has an oxidation state of +2. Sixteen radioactive isotopes have been derived from strontium through nuclear reactions.
The six halogens are bromine, chlorine, fluorine, iodine, tennessine and astatine. All halogen elements produce sodium salts. Sodium chloride is one example.
Hafnium is one of four elements in group 4 of the periodic table. Hafnium's oxidation state is +4, and this metal has a high tolerance for corrosion.
Group eleven elements include copper, silver, gold and roentgenium. With the possible exception of roentgenium, this group's elements share the same chemical traits which results from the common valence configuration.
Silicon, boron, germanium, arsenic, tellurium and antimony are considered metalloids. Currently, no conclusive description for a metalloid exists.
Noble gases are nonflammable gases. Except for helium and highly radioactive radon, all noble gases exist in the earth's atmosphere. Neon, argon, krypton and xenon are all noble gases.
Group 1 and group 2 elements, as well as helium, are included in the s-block. Potassium is a group 1 alkali metal. The s-orbital electrons of s-block elements readily react with other elements to form compounds.
Cadmium and copernicium are the other elements in the zinc group. Mercury is the only metal in the group that is liquid at room temperature.
Tungsten and seaborgium are elements in the chromium group with 2 valence electrons. Tungsten, chromium and molybdenum are refractory metals, which are durable and maintain structural properties at high levels of heat.
Manganese has an atomic number of 25 and five oxidation states: +2, +3, +4, +5, +6 and +7. Manganese forms a wide selection of compounds, including potassium permanganate, manganese oxide and manganese carbonate.
In addition to the benefits that phosphorus and nitrogen provide living things, these elements are also abundant in explosive weaponry. Bismuth, arsenic, antimony and moscovium are also group 15, nitrogen group elements.
Selenium is one of five reactive nonmetals that are solids. There are five reactive nonmetals that are gases, and one is a liquid.
The f-block of the periodic table includes period 6 lanthanides and period 7 actinides, which are all metals. F-block elements are also called inner transition metals.
Lithium has the symbol Li and atomic number 3. It's the first element of group 1, otherwise known as the lithium family. Group 1 elements are alkali metals.
Elements in group 2 of the periodic table are alkaline-earth metals that are also known as beryllium group elements. Alkaline-earth metal atoms readily lose electrons to become cations, or positive ions.
