Question

q1 chemistry: u2l14 electron config day 4 mad minute structure of the periodic table directions: write the group name or name of the family each statement belongs to. use the word box. note: each choice 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/15, halogens, group 6a/16 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:

Step1: Recall valence - electron property

Elements in Group 5A/15 have 5 valence electrons.

Step2: Recall reactivity with water

Alkali Metals react violently with water and form a + 1 charge when they react.

Step3: Recall non - reactivity

Noble Gases have full electron shells and do not like to react with other elements.

Step4: Recall valence - electron and charge

Elements in Group 3A/13 have 3 valence electrons and form a + 3 charge when reacting.

Step5: Recall phase property

Bromine in the Halogens exists in solid, liquid, and gas phases at room temperature.

Answer:

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