Explanation:
Atomic radius decreases from left to right in a period.
Therefore Calcium would have a smaller atomic size.
It should have 10 electrons
D. dormancy is the correct answer
Answer:
207g
Explanation:
Given compound:
Ca(ClO₃)₂
The equivalent mass can be derived by summing the molar masses of each atom
Molar mass of Ca = 40
Cl = 35.5
O = 16
Now solve;
Molar mass = 40 + 2(35.5 + 3(16)) = 207g
