Carbon would gain four electrons to obtain the nearest noble gas (neon) configuration but because of it's unique location in the Periodic Table carbon may also lose four electrons to obtain the Helium electron configuration. More often than not carbon forms ions through covalent bonding with other nonmetals like oxygen (carbonate) and nitrogen (cyanide).
Carbon gains four electrons to form carbide ions (C4-).

carbon has to gain or lose 4 electrons to gain noble gas configuration.
They achieve stable configuration by sharing their electrons in their outermost shell.
Nonmetals tend to form covalent bonds when reacting with one another. In covalent bonding, the atoms share valence electrons so that each atom will have a noble gas configuration of electrons, called an octet (8 electrons), except for hydrogen, which bonds to obtain the noble gas configuration of helium, which has 2 valence electrons.
Boron has an electronic configuration of 1s22s22p1 (it has 5 electrons). In order to reach the stable electron configuration of a noble gas with a completely filled valence shell, boron atom has to lose 3 electrons to obtain a stable duplet structure (i.e. 2 electrons in its first electron shell). After losing 3 electrons, the boron atom forms a B3+ ion, or a so-called tripositive ion.
It has a octet electronic configuration, which means the valence electrons (the outermost shells) are 8. So, they rarely can react as a electronic shell can hold up to 8 electrons and they don't need to lose or gain electron through reactions to obtain a stable structure (octet electronic configuration)
carbon has to gain or lose 4 electrons to gain noble gas configuration.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
They achieve stable configuration by sharing their electrons in their outermost shell.
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
Calcium loses two electrons to obtain a noble-gas electron configuration.
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
Gain two electrons to have the electron configuration as Argon
Nonmetals tend to form covalent bonds when reacting with one another. In covalent bonding, the atoms share valence electrons so that each atom will have a noble gas configuration of electrons, called an octet (8 electrons), except for hydrogen, which bonds to obtain the noble gas configuration of helium, which has 2 valence electrons.
Aluminium should gain 5 electrons or lose 3 electrons. It will normally lose 3 electrons to form Al3+ ion, rather than gaining 5 electrons and forming Al5- ion.
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
