In simplistic terms, an atom's electrons are held tot he atom because they are attracted to the positively charged nucleus. In larger atoms the electrons are farther away from that nucleus and there are usually more electrons in between, resulting in a weaker attraction.
Cations form when atoms lose electrons, they gain a positive charge as a result.
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
to become stable
They gain or lose electrons, while the atoms combine.
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.
Uranium loose electrons becoming a cation.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
When atoms lose electrons cations are produced.
When atoms lose or gain electrons, they form ions. These are charged particles.
Metals lose electrons.
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
Cations form when atoms lose electrons, they gain a positive charge as a result.
