Respuesta :
m= no of neutron+ number of proton
=8+8
=16
charge= number of electron- number of proton
=8-8
=0
hence, element is oxygen
Answer: The cation formed is [tex]O^+[/tex] ion
Explanation:
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation.
- When an atom gains electrons, it results in the formation of negative ion known as anion.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
We are given:
Number of protons = 8
Number of neutrons = 8
Number of electrons = 8
If the atom looses 1 electron, it will form a cation having +1 charge
The element having atomic number as '8' is oxygen
Hence, the cation formed is [tex]O^+[/tex] ion
