A covalent bond is when one or more pairs of electrons are shared between two atoms. The electrostatic forces that hold ions together in an ionic compound are called ionic bonds​ 1. Ionic bonds are formed between the attraction of cations and anions. 2. Covalent compounds exist only as molecules. 3. ionic compounds are crystals of ions. 4. In covelent compounds the atoms share electrons 5. Ionic compounds transfer atoms between metals and nonmetals.

Guide to naming and writing formulas for chemical coumpounds

Given- Carbon tetracloride Formula- CCl4

This is a covalent compoud therefore a prefix is needed. The prefix that is given is -Tetra- which means four. So the number of chlorines needed is four.



Given- C4H10 Name- Tetracarbon Decahydride

This is a covalent compound so a prefix is needed in the name. There are four carbons so the prefix is -Tetra- and there are ten Hydriogens, so the prefix is -Deca- <span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif;">Given- <span style="color: #00802a; font-family: Arial,Helvetica,sans-serif;">Phosphoric acid<span style="color: #00802a; font-family: Arial,Helvetica,sans-serif;">H3(PO4)

<span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif;">Formula- This is an Acid so Hydrogen has to come first. I from rule 3 that the second would be phosphate because it ends in -ic- so the inverse would be -ate-.



<span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif;">Given- <span style="color: #00802a; font-family: Arial,Helvetica,sans-serif;"> HBr <span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif;">Name- Hydrobromic Acid This is an acid. Rule number 1 tells me that the ending of Br is -ide- so you have to add -hydro- as a prefix and -ic- as a suffix.
