 What is a covalent bond?  A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms. -[]

What is an ionic bond?  A chemical bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. -[]

le 22 mars my compounds- ** sodium nitrate ** ionic cause sodium is a metal, so yeah. sodium has a +1 charge and nitrogen has a -3 charge because the periodic table tells me so. the formula is __S 3 N__.

<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif;"> **CF 3 ** covalenttt cause they're two nonmetals. so, since carbon had a charge of one, i just leave it alone since it is the first element. then, i found the prefix for 3, changed fluorine to fluoride, and put the suffix onto it. finally, the name is __carbon trifluoride__.



<span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif;"> H 3 PO 4 well, rule #3 applies cause PO4 is phosphate. you then chage -ate to -ic. therefore, it makes it __phosphoric acid__.

<span style="color: #ffff00; display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: center;">nitric acid well, you go off of rule 3, and get that the two elements are nitrogen and hydrogen. the cnarge of nitrogen is -3 and the charge of hydrogen is +1 finally, you have to cross charges and you get that the formula is __HNO 3. __
