Question 1

The forces btwn atoms that create chemical bonds are the = of interactions btwn

Answer 1

electrons

Question 2

Which one has a high boiling point, an Ionic or covalent compound?

Answer 2

Ionic

Question 3

What happens to the energy level and stability of two bonded atoms when they are separate and become individual atoms?

Answer 3

stability decreases and potential energy increases

Question 4

What is the chemical bonds in a solid substance is a excellent conductor of electricity?

Answer 4

metallic, bc valence e- are mobile

Question 5

Describe formation of a covalent bond

Answer 5

e- are shared

Question 6

describe formation of an ionic bond

Answer 6

e- are transferred from one atom to another

Question 7

describe metallic bonds

Answer 7

sea of e-‘s and free floating valence e- attracted to their positively charged metal ions

Question 8

Diff between INTRAmolecular forces and INTERmoleculear forces

Answer 8

Intra- forces within molecules due to covalent bonds (stronger)
INTER- forces btwn molecules due to their attraction

Question 9

What type of intermolecular force accounts for water’s high boiling point

Answer 9

the strength present of hydrogen bonds between water molecules (has strongest intermolecular force = high boiling point)

Question 10

How are hydrogen bonds different than regular dipole-dipole forces

Answer 10

it is the strongest force and are between N, O, F
