21
Q

What happens to electrons in a covalent bond?

A

Electrons are shared

22
Q

What type of elements are covalent bonds between?

A

Non-metals and non-metals

23
Q

Is a covalent bond a weak or a strong bond?

A

Weak bond

24
Q

What is a diatomic molecule?

A

Molecule made up of two of the same type of atom (Ex. H2)

25
Q

How many covalent bonds hold together two hyrdrogen atoms?

A

1

26
Q

How many covalent bonds hold together two oxygen atoms?

A

2

27
Q

How many covalent bonds hold together two nitrogen atoms?

A

3

28
Q

What is a polar covalent bond?

A

Unequal sharing of electrons

29
Q

How do polar molecules behave in solutions?

A

The partially positive side of one polar molecule is attracted to the partially negative side of the other polar molecule, causing the solute to dissolve into solution.

30
Q

In H2O, which atom(s) have the partial postive charge and which have the partial positive charge?

A

The O is partially negative because it has a stronger pull on the electrons while the H is partially positive

31
Q

What is the difference between an ionic compound and a molecular compound?

A

Ionic compounds involve atoms interacting through ionic bonds while molecular compounds involve atoms interacting through covalent bonds

32
Q

How is NaCl dissolved in H2O?

A

The partial negative side of H2O is attracted to the positive Na ion while the partial positive side of H2​O is attracted to the negative Cl ion. H2​O eventually surrounds each ion and causes it to dissolve

33
Q

What is a non-polar molecule?

A

A molecule without any partial or full charge (Ex: oil)

34
Q

Why don’t oil and water mix?

A

Oil is a non-polar molecule while water is a polar molecule. They are not attracted to each other because oil does not have a chagre while water has positive and negative ends.

35
Q

What is a hydrogen bond?

A

The partially positive H of one water molecule being attracted to the partially negative O of another water molecule

36
Q

What is a polar molecule?

A

A molecule with a partially positive and partially negative side
