Uranium is a donor of electrons.
valence electrons or electrons of the last level of electrons in an atom or the electrons in the last energy level of an atom, they have a negative chargethese electrons usually are the ones that take part in reacting, such as ionic bonding and covalent bonding :)
Alkali metals GIVE electrons (the only one electron that they do have) so that they may become balanced.
Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
Thede are unreactive elements.
Because in nature the elements seek to either give out electrons of take electrons. So the elements that gives out electrons bonds with the elements that takes electrons so that both of them are "happy"

Metals give up electrons while non-metals gain electrons
give
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
No
phosphorus will accept 3 electrons or share 3 electrons
neon has completely filled orbitals, obeys octet and has stable electronic configuration. Hence it does not take or give electrons.
It gives away electrons.
Alkali metals GIVE electrons (the only one electron that they do have) so that they may become balanced.
Carbon's electronic configuration is-2,4 and hence it has 4 electrons in the outer most shell. Therefore it is highly difficult for it to give electrons and highly difficult for it to be stable after gaining an additional 4 electrons. But Carbon does give and also take electrons under certain favourable conditions.
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
