Unit 5.2

Question 1

In what type of bond do two atoms share electrons in order to bond.

Answer 1

covalent bond

Question 2

What is electronegativity?

Answer 2

the measure of how strongly an atom attracts new bonding electrons to themselves

Question 3

In an ionic bonds, the atoms must be ___ charges.

Answer 3

opposite - one positive, one negative

Question 4

The formula for ionic bonds is a ___.

Answer 4

ratio

Question 5

In an ionic bond, what happens to electrons?

Answer 5

Electrons are released by the positive ion and taken by the negative ion.

Question 6

What type of covalent bond required atoms with equal electronegativity?

Answer 6

nonpolar covalent bonds

Question 7

How are covalent bonds formed?

Answer 7

Atoms pull on electrons from other atoms, pulling the two atoms together. As they near each other, the atoms begin to push apart, but are still being pulled together because of the electrons. This causes the potential energy in the atoms to decrease, forming a stable bond between them.

Question 8

What is required when writing covalent bond formulas.

Answer 8

put prefixes on elements
-ide at the end of the second element
mono- is not required on the first element.

Question 9

What prefix means 4?

Answer 9

tetra-

Question 10

N₂O

Answer 10

dinitrogen oxide
