Answer:
Copper = 2 Boron = 12 (copper and boron combined = 14)
Explanation:
the number after the element is the amount of atoms there is
Since the total amount of valence electrons is 3, it is in group 13 in the periodic table..therefore, it is specified as Boron.✅
Answer:
The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atom whereas a molecular formula gives the exact number of each atom in a molecule.
It’s ionic bond based on electrons gain/loss.
