Electrons are always negatively charged (-1 charge) Antiparticles of electrons, called positrons, have a positive (+1) charge.
if an atom gains an eletron it is more negative and ic called a anion

Eletron
About 9.109 x 10-31 kg.
DC Charge
Krypton has 8 valence electrons.
A neutral phosphorus atom has 15 electrons.
negative
The electron has a negative charge. It is found in the electron cloud around the nucleus.
FOR THE SIZEthe elements on the periodic tabledecreases across the periodand increases down the groupFOR THE ELECTRON DIFFERENCEFor the first 20 elementacross the period the difference between two closes element is +1 eletron or -1 eletrondown the group the difference between two closes element is +8 eletron or -8 eletron
It will lose one eletron
it is basically a model that shows the probability that an eletron exists in that position
