What are groups 1/12 on the periodic table?

What are groups 1/12 on the periodic table?

Lesson Summary

  • Group 1 of the periodic table consists of hydrogen and the alkali metals.
  • Group 2 consists of the alkaline Earth metals.
  • Groups 3–12 contain transition metals.
  • Groups 13–16 each contain at least one metalloid.
  • Group 17 contains halogens.
  • Group 18 consists of noble gases.

What is the 13 group called?

boron group
The boron group is sometimes called group 13 of the periodic table since the first member at the top of the group is boron (B). Even in this community, Boron is the only metalloid. All the metals are the other four elements in the group: aluminium (Al), gallium (Ga), indium (In), and thallium (Tl).

What are groups three through 12 called?

The elements in groups 3 through 12 on the periodic table are usually called transition metals.

What are the 12 groups on the periodic table?

Group 12, by modern IUPAC numbering, is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd) and mercury (Hg)….Physical and atomic properties.

Z Element No. of electrons/shell
30 zinc 2, 8, 18, 2
48 cadmium 2, 8, 18, 18, 2
80 mercury 2, 8, 18, 32, 18, 2

What is Group 1 called?

alkali metal
alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

What are the following groups known as Group 1?

Group 1 is known as the alkali metals.

What is the name for Group 14?

carbon group element
carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table—namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).

What is Group 15 called?

nitrogen group
Summary. Members of group 15 of the periodic table (15th vertical column) are summarised as group 15 elements (or the nitrogen group) consisting of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb) and bismuth (Bi).

What is Group 17 called?

halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

Which best describes groups 3 through 12 of the periodic table?

Periodic Table (Tabat)

Question Answer
What do the atomic numbers represent? Number of protons
What best describes groups 3 through group 12 of the periodic table? Transition metals
How is the periodic table used to identify properties of elements? By the group in which the elements are located

What are the 10 groups of the periodic table?

Terms in this set (10)

  • Alkali metals. Alkali metals Group 1: very reactive metals which do not occur freely in nature.
  • Alkaline Earth Metals. Group 2: next reactive metals, found in earths crust but not in elemental form.
  • Transition Elements.
  • Lanthanides and Actinides.
  • Boron Group.
  • Carbon Group.
  • Nitrogen Group.
  • Oxygen Group.

What are the groups called on the periodic table?

families
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
