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 needs to gain four electrons in order to obtain a noble gas electron configuration, similar to that of neon. This will result in a full valence shell with eight electrons, fulfilling the octet rule.
Ionic compounds obtain a stable electron configuration by transferring electrons from one atom to another to achieve a full outer shell. This transfer of electrons results in the formation of positive and negative ions that are attracted to each other by electrostatic forces, creating a stable compound.
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.
Fluorine is a nonmetal. It is located in group 17 of the periodic table. It tends to obtain an electron to form the fluoride ion.Fluorine is the element with highest electronegativity. So it does not tend to lose electrons. It is in the 17th group of the periodic table.
Carbon needs to gain four electrons in order to obtain a noble gas electron configuration, similar to that of neon. This will result in a full valence shell with eight electrons, fulfilling the octet rule.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
Hydrogen wants to obtain one electron to achieve a stable electron configuration similar to the noble gas helium.
Ionic compounds obtain a stable electron configuration by transferring electrons from one atom to another to achieve a full outer shell. This transfer of electrons results in the formation of positive and negative ions that are attracted to each other by electrostatic forces, creating a stable compound.
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
Calcium loses two electrons to obtain a noble-gas electron configuration.
You can achieve a stable electron configuration by using two electrons by forming a covalent bond with another atom that also has two valence electrons. In this way, each atom can share its valence electrons to achieve a full outer shell and achieve stability.
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.
Phosphorus has five valence electrons and needs to gain three additional electrons to achieve a stable noble gas electron configuration, similar to argon. By gaining three electrons, phosphorus can complete its outer shell with eight electrons, reaching stability. Therefore, phosphorus must gain three electrons.
Sulfur gains two electrons to attain a noble gas configuration, which is the electron configuration of argon. This allows sulfur to have a stable octet of electrons in its outer shell and achieve a more stable electron configuration.
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.
Gallium can obtain eight outer-shell electrons by forming covalent bonds with other elements that share electrons in a way that achieves a full octet, or by accepting electrons to achieve a stable electron configuration similar to a noble gas.
