Ionic Bonding and Isotopes

Question 1

what happens in ionic bonding?

Answer 1

atoms lose or gain electrons to form charged particles called ions which are then strongly attracted to one another.

this strong attraction is known as electrostatic attraction and gives ionic compounds their high melting and boiling points.

Question 2

what is it called when an atom loses electrons?

Answer 2

oxidation

Question 3

what is it called when an atom gains electrons?

Answer 3

reduction

Question 4

which four groups are most likely to form ions?

Answer 4

groups 1+2

groups 6+7

Question 5

groups 1+2 are

Answer 5

metals that lose electrons to for cations

Question 6

groups 6+7 are

Answer 6

non-metals that gain electrons to form anions

Question 7

what is an isotope

Answer 7

isotopes are atoms of the same element that have the same number of protons but a different nucleon number

Question 8

the number of _____ in the _____ _______ determines the ______ ______

Answer 8

electrons, outer shell, chemical properties

Question 9

what are two other features of isotopes?

Answer 9

they have similar chemical properties as they have the same number of electrons in the outer shell

they have different physical properties as they have different masses

Question 10

relative atomic mass takes ____________

Answer 10

all stable isotopes into account
