To make a positive ion, we need to remove one or more of the negative components from an atom. The negative charges that make up an atom are the electrons, which can be found in shells or orbitals some distance from the nucleus. Take away one or more electrons, and the protons, the positive charges that make up atoms and which hang out in the nucleus, give the atom an overall positive charge. An atom that has lost one or more electrons becomes a positive ion.

If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
Electrons acquire steady velocity because the acceleration acquired is lost in collisions with positive ions of the metals.
It has lost electrons, resulting in a more positive charge.
Atoms that have lost electrons are positive ions, and are called cations.
2 electrons are lost from calcium, forming Ca2+ ion
Electrons are both gained and lost. Electrons are both gained and lost.
two electrons lost
it has gain 4 electrons
Reduction Is Gain of electrons
In a redox reaction the number of electrons lost by one particle is equal to the number of electrons gained by another particle.
Lost because it is easier for the element to lose 3 electrons and become an octet than it is to gain 5 electrons.
Usually three will be lost.
Chlorine gain electrons.
Argon
Yes. two electrons is lost.
