all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
It becomes positive.
it loses 2 electrons
it gets positive charge
an atom loses electrons and becomes positivly charged
The ATOM decreases in size when it loses an electron and increases when electrons are added.
When Cr3+ forms, the neutral atom (chromium) loses 3 electrons. This happens because the neutral chromium atom has 24 electrons, but when it forms Cr3+, it loses 3 electrons to have a total of 21 electrons.
The mass become lower but the difference is not significant.
It becomes a positively charged ion known as a cation.
The category that loses electrons easily is the metals.
When an atom loses electrons it becomes ionized and more positive a charge. Losing an electron can cause this atom to react with other atoms.
The object that loses electrons becomes positively charged, as it has more positive protons than negative electrons. This imbalance in charge may cause the object to attract other objects with a negative charge.
Cations are formed when elements lose electrons. Then they get positively charged.
