Non-metals and non-metals

Question 23

Is a covalent bond a weak or a strong bond?

Answer 23

Weak bond

Question 24

Answer 24

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

Question 25

How many covalent bonds hold together two hyrdrogen atoms?

Answer 25

1

Question 26

How many covalent bonds hold together two oxygen atoms?

Answer 26

2

Question 27

How many covalent bonds hold together two nitrogen atoms?

Answer 27

3

Question 28

What is a polar covalent bond?

Answer 28

Unequal sharing of electrons

Question 29

How do polar molecules behave in solutions?

Answer 29

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.

Question 30

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

Answer 30

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

Question 31

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

Answer 31

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

Question 32

How is NaCl dissolved in H₂O?

Answer 32

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

Question 33

What is a non-polar molecule?

Answer 33

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

Question 34

Why don't oil and water mix?

Answer 34

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.

Question 35

What is a hydrogen bond?

Answer 35

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

Question 36

What is a polar molecule?

Answer 36

A molecule with a partially positive and partially negative side
