The symbol P is for phosphorus having atomic number 15. That means it has 15 protons and 15 electrons in its neutral state.

The given symbol P^{3-} has a -3 charge that means it has gained 3 electrons so, the number of electrons in the P^{3-} is: 15+3 = 18. The number of protons will remain same that is the number of protons = 15.

So, the ion P^{3-} has 15 protons and 18 electrons that gives 15-18=-3 charge on the P^{3-} ion.

So, the answer is 15 , 18.

Answer:

0.2007 nm

3.57 cm

0.01478 g

8280000 pg

Explanation:

1)200.7 pm

1 picometer is equal to 0.001 nanometer.

1 nm = 1000 pm

200.7 pm× 1 nm / 1000 pm  = 0.2007 nm

2)0.000357 hm

1 hectometer is equal to 10,000 centimeter.

1 hc = 10,000 cm

0.000357 hc× 10,000 cm / 1 hc = 3.57 cm

3) 14.78 mg

1 gram is equal to 1000 milligram.

1 g = 1000 mg

14.78 mg × 1 g/1000 mg = 0.01478 g

4)8.280 µg

1 microgram is equal to 10⁶ picogram.

1 µg = 1000000 pg

8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg
