Ionic compounds are compounds made up of elements in which one has the tendency to loose electrons whereas the other has the tendency to gain electrons. Loss of electron results in the formation of a positively charged ion (cation) while gain of electrons results in the formation of negatively charged ions (anions). Usually metals have the tendency to loose electrons and non-metals tend to gain electrons.
Calcium (Ca) is a metal and belongs to group IIA in the periodic table with a valence electron configuration of 4s2
Fluorine (F) is a non-metal and belongs to group VIIA in the periodic table with a valence configuration of 2s22p5.
Thus, Ca will donate its outer 2 electrons to F, thus allowing each of the electronegative F atoms to complete its octet.
Therefore, we have:
Ca2+ + F- ------ CaF2
Answer:
the Mercury planet is likely to have life but the earth as a lot of oxygen
Answer:
2Li + 2H2O → 2LiOH + H2
Explanation:
Lithium + Water = Lithium Hydroxide + Dihydrogen
Explanation:
In this problem, we are given a conversion factor.

So, since we know this, we can simply multiply 25 by 6.5 to see what the distance will be.
25 * 6.5 = 162.5
So, the distance traveled for 25 seconds is 162.5 miles.
