What are the two groups of the periodic table?
The elements can also be divided into two main groups, the metals and the non-metals.
What is the difference between group 1 and group 2 on the periodic table?
The key difference between group 1 and group 2 elements is that all group 1 elements have unpaired electrons in their outermost orbital, whereas group 2 elements have paired electrons in their outermost orbital. Groups 1 and 2 of the periodic table contain s block elements.
What are groups one two on the periodic table?
For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.
What are the group 3 elements called?
Group 3A. Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.
What are the 8 groups in the periodic table?
The following are the 8 groups of the periodic table:
- Alkali metals.
- Alkaline earth metals.
- Rare earth metals.
- Noble gases.
What is Group 7 on the periodic table called?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is Group 8 on the periodic table called?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Is Group 13 metal or nonmetal?
Groups 13–16 of the periodic table contain one or more metalloids, in addition to metals, nonmetals, or both. Group 13 is called the boron group, and boron is the only metalloid in this group. The other group 13 elements are metals. Group 14 is called the carbon group.
