What is the symbol of a ion with a 22 protons, 34 neutrons, and 18 electrons
Dominik [7]
Well knowing the number of protons, you can find what the element is, which is Ti = titanium. Then to find the charge, simply subtract 22 and 18 which is +3.

Find the mass number by adding 22 and 34 = 56.

56. +3
Ti

22

This would be the correct notation in isotopic form.

Murljashka [212]

Answer:

d = 0.93 g/cm³

Explanation:

Given data:

Mass of object = 28 g

Volume of object = 3cm×2cm×5cm

density of object = ?

Solution:

Volume of object = 3cm × 2cm ×5cm

Volume of object = 30 cm³

Density of object:

d = m/v

by putting values,

d = 28 g/ 30 cm³

d = 0.93 g/cm³
