Question

Complete the ion symbol for the atom below

Answer 1

The symbol : $\tt _5^{10}B^{+3}$

Further explanation

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

In the picture above :

Protons = 5

Neutrons = 5

Both are located in the atomic nucleus (red and blue)

Electrons = 2

Located in the atomic shell

So :

the atomic number = number of protons = 5

the mass number = protons+neutrons = 5+5=10

charge of atom = protons-electrons=5-2=+3

The element with atomic number 5 is Boron

symbol :

$\tt _5^{10}B^{+3}$
