Unit A

Question 1

What is a chemical bond

Answer 1

A chemical bond is a bond that keeps elements together with a force calling “intermolecular forces”

Question 2

What is an ionic bond

Answer 2

An ionic bond is a chemical bond with a metal and a non metal which together shares their electrons to satisfy each others valence orbitals

Question 3

What is a covalent bond

Answer 3

a covalent bond is a chemical bond between molecular compounds

Question 4

What is electronegativity

Answer 4

Is the ability of an atom being able to attract electrons

Question 5

in the context of electronegativity how could u differentiate ionic, polar and non polar

Answer 5

Ionic: above 1.7 en
Polar: more than 0.4 en and less than 1.7 en
Non polar: below 0.4 en

Question 6

What is polarity?

Answer 6

Polarity is when there is a slightly positive charged side and a slightly negative charged side because of the unequal distribution of electrons

Question 7

How do we know if something is polar

Answer 7

if there is lone pairs or if the shape is not symmetrical

Question 8

How do we know if something is non polar?

Answer 8

if there is symmetry

Question 9

explain what a valence electron and how its important for bonding

Answer 9

A valence electron is an electron orbiting on the most outer shell of an atom. These are important in bonding because they are the reason different atoms interact with each other. Valence electrons are shared between two different atoms in order to become stable.

Question 10

Difference between intramolecular and intermolecular forces

Answer 10

Intramolecular is what holds the atoms together when bonded while intermolecular is the attraction or repulsion between molecules

Question 11

What is a hydrogen bond

Answer 11

is a strong type of intermolecular force and is when hydrogen directly reacts with either fluorine, nitrogen or oxygen

Question 12

What is London forces

Question 13

What is Dipole Dipole forces

Question 14

What is Lewis dot diagrams?
