Answer 19

ionic compound

Question 20

why are covalent compounds more flammable than ionic compounds?

Answer 20

covalent compounds are more likely to contain carbon and hydrogen atoms than ionic compounds

Question 21

which compound has the ability to conduct heat and electricity?

Answer 21

ionic compound

Question 22

which compound type works as an insulator?

Answer 22

covalent compound

Question 23

why are atoms present in covalent compounds less attracted to each other compared to ionic compounds?

Answer 23

covalent compounds share valence electrons while ionic compounds give them away

Question 24

why do ionic compounds take the form of crystalline solids?

Answer 24

they take the form of matrixes instead of molecules

Question 25

which charges show strong attraction to each other?

Answer 25

positive (+) and negative (-) charges

Question 26

define crystal lattices

Answer 26

symmetrical three-dimensional formation of atoms in a crystal

Question 27

what is polarity in a compound?

Answer 27

polarity in a compound is the result of the distribution of an electrical charge within atoms formed through chemical bonding.

Question 28

define electronegativity

Answer 28

electronegativity is an atom’s ability to attract electrons to form a chemical bond

Question 29

how are compounds formed?

Answer 29

compounds are formed when 2 or more elements bond together

Question 30

what chemically bonds elements?

Answer 30

electrostatic edforces

Question 31

what makes covalent compounds less efficient in transferring heat?

Answer 31

heat does not travel well in covalent compounds since they take the form of molecules, making them loosely packed

Question 32

what is an ion?

Answer 32

an atom with a charge

Question 33

describe inert atoms

Answer 33

inert atoms are unable to gain or lose electrons, making them unable to perform chemical reactions
