Answer:
The answer to your question is 12
Explanation:
Data
Number of electrons in Phosphorus 3+ ion
Process
1.- The sign of the number after the name indicates if the element has lost or gained electrons.
If the sign is positive the element has lost electrons
If the sign is negative the element has gained electrons.
2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.
what are the options?
reply in comments so i can help:)
The new pressure of the gas would be 505.58 torr
<h3>Boyle's law</h3>
According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.
This can be mathematically represented as: P1V1 = P2V2
In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL
Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr

Explanation:
The answer is halogens
Halogens are reactive non metallic elements that form strongly acidic compounds with Hydrogen to form simple salts
