directions: write the group name or name of the family each statement belongs to. use the word box.
note: each box may be used more than once or none at all.
transition metals
alkaline earth metals
group 3a/13
alkali metals
group 5a/15
noble gases
group 4a/14
halogens
group 6a/16
statement which group?

1. i am the only group that contains elements with five valence electrons.
2. i am a group that reacts violently with water, and i like forming +1 charge when i react.
3. i am the only group that does not like to react with other elements. all of the elements in my group have full shell.
4. elements in our family have 3 valence electrons and we like to form +3 charge when reacting with other elements.
5. i am the only group that contains an element in its solid, liquid and gas phase at room temperature.

Explanation:

1. Group 5A/15 elements have 5 valence - electrons.
2. Alkali Metals react violently with water and form a + 1 charge when they react.
3. Noble Gases have full - shells and are unreactive.
4. Group 3A/13 elements have 3 valence electrons and form a + 3 charge when reacting.
5. Group 6A/16 contains bromine which is in solid, liquid, and gas phases at different conditions close to room temperature.

Answer:

1. Group 5A/15
2. Alkali Metals
3. Noble Gases
4. Group 3A/13
5. Group 6A/16
