Alkali Metals, except for Hydrogen, which is a Nonmetal.
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
The halogens are a group of elements in the periodic table consisting of fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive nonmetals that readily form salts with metals.
Each column is a group of chemical elements.
elements are in the same group since they react similarly to other elements in that group.
main group elements
There is a total of 17 elements in those groups.
No. noble gases are group VIIIA or group 18 elements
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
group 2 elements are alkaline elements.one of the element in d group is berrylium
Group one elements are the alkali metals.
