I’m sorry it’s a bit messy but If you need me to tell you any of the numbers that are hard to see just let me know!
Explanation:
- Isotopes are defined as atoms of the same element but differ in the number of neutrons in their nucleus where a number of protons and electrons remain the same.
- Ions are defined as chemical species of an atom with an electrical charge.IO with a positive charge are called cations, and ions with a negative charge are called anions.
- Atom has three subatomic particles: protons, electrons, neutrons
- Atomic number (Z)= Number of protons
- Number proton = Number of electrons (isoelectric neutral atom)
- Atomic mass (A)= Number of protons + Number of neutrons
The chemical symbol of an element X is written as:[tex]^A_ZX^C[/tex]
Where : Charge on ion = C
