Give the ion symbol for the ion that has 27 protons and 24 electrons.
Natalija [7]

Answer:

Z³⁺

Explanation:

The ion symbol can be depicted as Z³⁺ .

In this atom, the number of protons is 27 and the number of electrons is 24.

Protons are the positively charged particles within an atom.

Electrons are the negatively charged particles within an atom.

 To find the charge;

   Charge  = Number of protons  - number of electrons

  Charge  = 27   - 24  = +3

The atom is positively charged and it can be depicted as Z³⁺

Calculate these masses.
Alex
A) mass / volume = density
m/6.00cm3 = 13.5939g/cm3
m = 13.5939g/cm3 • 6.00cm3
m = 81.6g

B) mass / volume = density
m/25.0cm3 = 0.702g/cm3
m = 0.702cm3 • 25.0g/cm3
m = 17.6g

1mL = 1cm3
