Elements in a group have the same number of electrons in their outer orbital.
because they vhave lasers in there eyes
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.
Group IA or group 1 elements are known as alkali metals.
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
