Chapter 5 Chemical bonding

Question 1

compound

Answer 1

substance made up of two or more different elements that are combined together chemically

Question 2

octet rule

Answer 2

when bonding occurs atoms tend to reach an electron arrangement with eight electrons in the outermost energy level

Question 3

ion

Answer 3

charged atom/ group of atoms

Question 4

trends in the transfer of electrons (groups)

Answer 4

group 1 =lose 1 electron and form 1 pos. charge, Group 2 = tends to lose 2 electrons (valency)

Question 5

pos. ions

Answer 5

cations

Question 6

neg. ions

Answer 6

anions

Question 7

ionic bond

Answer 7

force of attraction bet. oppositely charged ions in a compound , always formed by the complete transfer of electrons from 1 to another

Question 8

drawing electron dot - crosses diagrams

Answer 8

dots= actually outer electrons of an atom Crosses= electrons of the other atom
