CaS. Calcium is in group 2 and forms the Ca2+ ion, sulfur is in group 16 and forms the sulfide ion, S2-.
CaF2
AlF3. Aluminum trifluoride.
Ammonia consists of the elements called Nitrogen and Hydrogen, froming the formula NH3.
Rule of thumb answer is covalent bonds form between non metal elements.
group 1 elements.
CaF2
Ca2+ + 2 I- --> CaI2
AlF3. Aluminum trifluoride.
Ca2+ + 2 I- --> CaI2
Al3+ and 3 Cl- form AlCl3This chemical is a great catalyst for organic chemists- in Friedel-Krafts and chlorination of benzene.
Ammonia consists of the elements called Nitrogen and Hydrogen, froming the formula NH3.
The ionic compound formed by reaction of the elements with atomic symbols K and O is named potassium oxide and has the formula unit K2O. (The lower case letters k and o are never proper atomic symbols!)
Rule of thumb answer is covalent bonds form between non metal elements.
group 1 elements.
Nitrogen, oxygen, and the combined element to form nitrate.
Yes; these elements can form an ionic compound named calcium sulfide, with formula CaS.
