Explanation:
It is known for a neutral atom number of protons equal the number of electrons. But since, it is given that there are 19 electrons so it means that the atom already has +3 charge.
Also, number of protons of an atom represent its atomic number. And when an atom loses an electron then it acquires a positive charge. When an atom gains an electron then it acquires a negative charge.
Here, because the atom loses an electron therefore, the net charge on the atom is now +4.
Answer: The net charge on the atom is of +4 units.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in a neutral atom. It is represented as Z.
Z = Atomic number = Number of protons = Number of electrons
An ion is formed when an atom looses or gains electrons. When an atom looses electrons, it leads to the formation of a positively charged ion known as cation and when an atom gains electrons, it leads to the formation of negatively charged ion known as anion.
We are given:
An atom containing 22 protons and also 19 electrons.
This means that the given atom has lost 3 electrons and carries a positive charge of +3 units.
When this atom again looses 1 electron, it will lead to the formation of positive ion having +4 units.
Hence, the net charge on the atom is of +4 units.
