Beryllium- 1s2, 2s2 or [He] 2s2
Magnesium- 1s2, 2s2, 2p6, 3s2 or [Ne] 3s2
Calcium- 1s2, 2s2, 2p6, 3s2, 3p6,4s2 or [Ar] 4s2
Strontium- 1s2, 2s2, 2p6,3s2,3p6, 4s2, 3d10, 4p6,5s2 or [Kr] 5s2
Looks like seven valance electrons to me. that would make this group the halogens, 7A.
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
because they have completely filled electronic configuration.
The electron configuration 1s2 2s2 sp6 3s2 3p6 3d1 4s2 belongs to the group of transition metals. It is the electron configuration of the element titanium (Ti), which is a transition metal with atomic number 22.
It is in Group O or Group 8. Also known as noble gas, they do not react with other elements as they do not have to react to get a stable configuration.

The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
They all have 2 electrons in their outer shells.
because they have completely filled electronic configuration.
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
This electron configuration belongs to the group 17 elements, also known as the halogens. The 3s2 3p5 configuration specifically corresponds to the element chlorine (Cl).
The electron configuration 1s2 2s2 sp6 3s2 3p6 3d1 4s2 belongs to the group of transition metals. It is the electron configuration of the element titanium (Ti), which is a transition metal with atomic number 22.
The general electronic configuration of nitrogen group elements is ns2np3, where "n" represents the valence shell. Each element in this group has 5 valence electrons, with 2 in the s orbital and 3 in the p orbital. This configuration gives these elements similar chemical properties, such as the tendency to form covalent bonds.
