Well, an atom that loses an electron does not just "lose" it in space, the electron is taken away by another atom or molecule. So the electron sticks to the new molecule and forms an ion with a charge (given that the original atom was a neutral one). When this happens inside the body some really dangerous compounds can be formed, these are called "free radicals"
Loses two electrons.
This atom become a positive ion (cation).
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When an atom loses or gains electrons, it becomes an ion.
This single atom remain an atom of krypton !
it gets positive charge
all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
an atom loses electrons and becomes positivly charged
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.
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.
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
The ATOM decreases in size when it loses an electron and increases when electrons are added.
Loses two electrons.
It becomes a positively charged ion known as a cation.
The mass become lower but the difference is not significant.
This atom become a positive ion (cation).
An atom that loses one or more electrons is an ion, specifically a cation.
