Uranium loose electrons becoming a cation.
that usually depend what type of atoms they are. Certain atoms lose electrons, others do not.
Uranium, as a metal, lose electrons.
lose
Calcium is most likely to lose two electrons to form its dipositive ion.
If an atom has three electrons, it will have one valence electron (valance = outer shell). It will be more likely to lose an electron than gain one, since it has only one to lose, but seven to gain.
Covalent bonds do not gain or lose electrons, but rather share electrons.
Either lose 5 electrons, which is least likely, or gain 3 electrons.
Polonium lose electrons.
Calcium is most likely to lose two electrons to form its dipositive ion.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
If an atom has three electrons, it will have one valence electron (valance = outer shell). It will be more likely to lose an electron than gain one, since it has only one to lose, but seven to gain.
Covalent bonds do not gain or lose electrons, but rather share electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
Lose
Either lose 5 electrons, which is least likely, or gain 3 electrons.
High Electonegativity of non metals makes them more likely to gain electrons.
Group 13 has an oxidation number of 3+ so it is more likely to lose electrons than gain them, but it is possible that it gains them
When atoms lose or gain electrons, they form ions. These are charged particles.
Se will gain electrons
They have relatively full valence shells.
