Answer:
This is because their atoms have the same number of electrons in the highest occupied energy level. Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.
Explanation:
Answer:
V3− B) A nonmetal that gained three electrons
X− A) A nonmetal that gained one electron
Y+ C) A metal that lost one electron
Z3+ D) A metal that lost three electrons
Explanation:
As per the Octet rule, each atom must have eight electrons in its outermost shell.
The non-metals gain electrons while reacting to reach the configurations of noble gas as they possess lower Ionization ability and higher electro-negativity. Thus, they will have a negative charge(V3 -, X-)
Metals, on the other hand, lose electrons to reach a stable octet configuration due to the higher electro-positivity and lower electron affinity. Therefore, they will have a positive charge(Y+, Z3+).
Time Zones were adopted to fix the time. Without the time zone, you will never know what time it is
