Chemical Bonding

Why do all bonds form?

• To fill up the outer shell.

• To achieve the one or duplet electronic configuration

An atom with 1 valence electron 'needs' a full shell, so it can either gain 7 electrons or lose 1. Which is more likely to occur?

• lose 1 electron

• gain 7 electrons

What two types of atoms make a covalent bond?

• metal atom and metal atom

• metal atom and non metal non atom

• non metal atom and non metal atom

When an atom loses an electron, it becomes a _________.

• noble gas

• anion

• cation

Atoms are most stable when their outer shell is full or complete.

• True

• False

Atoms involved in a covalent bond are not charged, while atoms involved in an ionic bond are charged (negative or positive)

• True

• False

What part of an atom is involved in chemical bonding?

• proton

• neutron

• electron

How many valence electrons does hydrogen have?

• 1

• 2

• 3

• 4

Low melting point and low solubility in water are general properties of ______________________ compounds

• ionic

• covalent

• all

Where are the non-metals located on the periodic table?

• all over

• On the left side of the "staircase"

• On the right side of the "staircase"
