Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used.
the number above the element’s symbol is the element’s atomic number. match each element with the number of valence electrons it has.

4= Si

5=P

3= Al

6= S

2= Mg

Explanation:

4 → Si

Silicon is part of the carbon group and has 14 electrons, spread over 3 shells:

⇒ on the first shell (K) 2 electrons

⇒on the second shell (L) 8 electrons

⇒ on the third shell (M) the remaining electrons : 14-8-2 = 4

5 → P

phosphorus  is part of the nitrogen group and has 15 electrons, spread over 3 shells:

⇒ on the first shell (K) 2 electrons

⇒on the second shell (L) 8 electrons

⇒ on the third shell (M) the remaining electrons : 15-8-2 = 5

3 → Al

Aluminium is part of the Boron group and has 13 electrons, spread over 3 shells:

⇒ on the first shell (K) 2 electrons

⇒on the second shell (L) 8 electrons

⇒ on the third shell (M) the remaining electrons : 13-8-2 = 3

6 → S

Sulfur is part of the oxygen group and has 16 electrons, spread over 3 shells:

⇒ on the first shell (K) 2 electrons

⇒on the second shell (L) 8 electrons

⇒ on the third shell (M) the remaining electrons : 16-8-2 = 6

2 → Mg

Magnesium is part of the Beryllium or alkaline earth metals group and has 12 electrons, spread over 3 shells:

⇒ on the first shell (K) 2 electrons

⇒on the second shell (L) 8 electrons

⇒ on the third shell (M) the remaining electrons : 12-8-2 = 2

oh it is true if thats what you are asking

the correct answer would be b) volume versus temperature, because they are also directly proportional.
