What is the first thing you need to do when drawing Lewis Structures?

Count the number of valence electrons

Subtract to make the valence number even

Add to make the valence number even

After drawing in your bonds, what do you do if you don't have enough electrons to get each atom to its octet?

Place dots until everything has eight

Place dots only around the terminal atoms

Have eight only around the central atom

In a Lewis structure, what do you do with the total number of valence if your ion is 2- charged?

Subtract 2 from the valence number

Multiply the valence number by 2

In a Lewis structure, what do you do with the total number of valence if your ion is + charged?

Subtract 1 from the valence number

Multiply the valence number by 1

What is the basis of a metallic bond?

the attraction between positive metal ions and free floating electrons.

the attraction of neutral metal atoms.

the attraction between protons and neutrons.

the attraction between positive metal ions and interlocking electrons.

Why do metals conduct electricity?

The electrons are delocalised and able to move.

The electrons are held tightly within the lattice.

The electrons are shared between two metal ions.

In chemical compounds, covalent bonds form when

pairs of electrons are shared between two nonmetal atoms.

the electronegativity difference between two atoms is very large.

electrons are completely transferred between two metals.

two nonmetal atoms are attracted to each other by opposite charges.
