Complete the ion symbol for the atom below

The symbol :

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 :

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
