NH3

Question 5

diatomic molecules

Answer 5

contain 2 atoms, can be of the smae type of different

Question 6

polyatomic molecules

Answer 6

contain more than 2 atoms, can be of the same or different element

Question 7

what is ccovalent bonding

Answer 7

sharing of a pair/pairs of electrons between non metal atoms to gain stable valence shells

Question 8

which bonds are the strongest

Answer 8

those that share the most electrons

Question 9

what holds the atoms together in a covalent bond

Answer 9

electrostatic attraction between the positive nucleus and electrons

Question 10

types of covalent bonds

Answer 10

single, double and triple

Question 11

what are molecular formulas

Answer 11

depict the number of each type of elements present in a compound but does not offer any info about the structure of bonding

Question 12

lewis structure/electron dot diagram

Answer 12

diagrams that illustrate the number of valence electrons that an atom has, with dots representing electrons

Question 13

octect rule

Answer 13

many atooms become more stable if they have 8 electrons in their valence shell

Question 14

can molecular substances conduct electricity

Answer 14

no, they are neutral overall and dont have free moving charged particles
