 * **Formation:** || A __ covalent bond __ is formed between two non-metals that have similar electronegativities. Neither __ atom __ is "strong" enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular __ orbit __ with others || An ionic bond is formed between a __ metal __ and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond. || hide ||

 * **What is it?:** || Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent __ bonds __ . || Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. These kinds of bonds occur mainly between a metallic and a non metallic atom. || hide ||

1.) HF. hydrofluoric. I know this because flourine ends in a -ide so u use da 3rd rule. Therefore you add hydro to the beggining and ic 2 the end.

2.)Fe(OH)3. iron(iii)hydroxide I know this because Fe is iron and a non-metal so it needs a number. OH3 has a -3 so Fe has to +3.

3.) calcium silicate. HCaSi. I know this because of Ca is calcium and Si is silicate.

4.)hydroselenic acid. HSe I know this because of rule 2. H IS FOR DA ACID AND SE IS FOR HYDROSELENIC>
