Protons (from the nucleus) have a positive charge and electrons (from the electron cloud) have a negative charge. A normal atom is neutral, because the number of electrons is equal to the number of protons.
what changes the charge of the atom
The charge of an unionized atom is negative.
A neutral atom will have a charge of ZERO
An atom with an electrical charge is called an ion.
An atom may have a positive charge, a negative charge, or no charge. If it has a non-zero charge, it is said to be an ion.
No matter where an electron happens to be -- in an atom, outside of an atom, near an atom -- its charge will ALWAYS be negative one atomic charge.
An atom with positive charge is cation.An atom with negative charge is anion.
The neutral atom hasn't a charge.
When an atom has an electric charge it is called an ion.
An ion is an atom with a positive or negative charge.
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
when an electrophile attacks 2nd position in pyridine the +ve charge goes on the electronegative nitrogen atom and destabilizes the intermediate ,in case of 3rd position attack the +ve charge goes on the ring which is more stable than the intermediate formed during the 2nd position attack
