6. How do you know the number of covalent bonds between two nonmetals? (based on the number of electrons they need to meet the octet. For example: nitrogen has 5 valence electrons, it needs another three valence electrons to become 8. Two Natoms share three pairs of electrons and they form triple bond. O2: double bond, halogen: single bond.) 7. How many valence electrons that an element need to form a negative ion? (to see how many valence electrons to...
