Just as a dozen is 12 of something, a mole is about 6.02 * 10^23 of something .
Answer:
C
Explanation:
it belong to that group as it needs 1 electron to be chemically stable
Volume= mass divided by density
V= m/d
55/3.23
= 17.03
Phosphorus is in group 15 meaning it have 5 valence electrons. This means that it needs 3 more electrons to create a full outer shell. As these three electrons are negatively charged it means that P is a 3- ion (it’s an anion [negatively charged ion])
