uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuum i thinkitis the way its shaped
Calcium fluoride.
Ca is metal, F is non-metal, so they form ionic bond.
Ca as metal can form only positive ion. Ca in the second group, so the charge of Ca ion is 2+. Ca²⁺
F is in the 17th group, so it has 7 electrons on the last level. It is non-metal, non-metal, so it has negative charge -(8-7)=-1. "8" because on the last level cannot be more than 8 electrons. F-ion is F¹⁻.
Ca²⁺ F¹⁻
Number of positive charges should be equal to number of negative charges,
Formula of calcium fluoride
CaF2.
2 atoms Fluorine bond with Calcium.
Just look it up on goog^le or a chart
The number of significant figures in 369,132,000 is 6
And this is y I should of paid attention in that one science class in middle school that taught this...
