Answer 2

a million.) a. very low reactivity - those are the noble gases and they have were given filled outer shells so as that they do no longer might want to prefer to react with diverse elements to benefit octets, (he's satisfied utilizing reality it in hassle-free words has a million potential factor and has its duet, (2 electrons) - utilizing reality of this they have very low reactivity.) 2.) halogens, at the same time as they replace into ions, (income a million electrons at the same time as they react with maximum metals), they are called halides) 3.) b. are very reactive elements - they are very reative utilizing reality they have a million valence electron. they settle on to lose this valence electron in order that as that they'd have a sturdy octet of their second to the finest potential factor, ex. Na: 1s2 2s2 2p6 3s1 -if Na loses its 3s1 electron it might want to have an complete octet contained contained in the second one potential factor: 2s2 2p6. hence, dropping a million electron demands that it reacts with nonmetals or molecular or ionic compounds to variety a sturdy compound. it gained't in any recognize only keep that one valence electron so because it really is why it truly is continually present day in a compound.
