Question

draw the lewis dot symbols for the following atoms/ions. part 1 of 2 p part 2 of 2 sr²⁺

Explanation:

Step1: Determine valence electrons of P

Phosphorus (P) is in group 15, so it has 5 valence electrons.

Step2: Draw Lewis - dot symbol for P

Place the symbol 'P' and then place 5 dots around it, with a maximum of 2 dots per side. So the Lewis - dot symbol for P is: P with one dot on the top, bottom, left, and two dots on the right.

Step3: Determine valence electrons of Sr²⁺

Strontium (Sr) is in group 2 and has 2 valence electrons. Sr²⁺ has lost 2 electrons. So it has 0 valence electrons.

Step4: Draw Lewis - dot symbol for Sr²⁺

The Lewis - dot symbol for Sr²⁺ is just the symbol Sr²⁺ with no dots around it.

Answer:

P: Place the symbol 'P' with one dot on the top, bottom, left, and two dots on the right.
Sr²⁺: Just the symbol Sr²⁺ with no dots around it.
