Answer:
On the left side of calcium atom.
Explanation:
There are two dots are present on the left side of calcium atom which represents the unpaired electrons present in the outermost shell. This structure is presented by Lewis in order to show the number of unpaired electrons in the atom. if the calcium atom loses these two electron during a chemical reaction so the two dots disappear and the calcium atom is now stable.
Answer:
1st column group 1 - group2
second column Halogen group - zero group ( inert gases )
third column - very active metals , tend to lose one electron -less reactive than group one , tend to lose 2 electrons - very active nonmetals, tend to gain one electron - Nobel gases , do not gain or lose electrons
Explanation:
