What happens if an atom loses a valence electron

Metal atoms form positive ions, while non-metal atoms form negative ions. A decrease in the motion of the atoms allows the attractions between atoms to bring them a little close together. Metals lose electrons, nonmetals gain electrons In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion.

These compounds gain an electron during a chemical reaction to become stable and complete their octet for the last electron shell. It has two electrons in its outer shell. All atoms tend to seek to be stable, which occurs when they have a neutral charge.

This level has eight electrons Atomic number of fluorine F is 9, with electronic configuration; 2,7. Chlorine gains an electron, leaving it with 17 protons and 18 electrons. Found inside — Page 27When an atom loses one or more electrons , it becomes a positive ion and its radius Atoms attain a stable valence electron configuration by bonding with Electrons can also be excited by electrical excitation, where the original electron absorbs the energy of another, energetic electron.

The atom then loses or gains a "negative" charge. This gives the oxygen the extra electrons it needs. Answer: When an atom loses an electron, it becomes a cation positive ion.

Others gain electrons and become negative ions. Found inside — Page Only electrons are involved in chemical changes; the nuclei of atoms are not Therefore, it is very reactive and gives up electrons in chemical reactions. A hydrogen atom is therefore often referred to as just a proton, as it is left with only one proton and no electrons, as a H atom only has one of each.

How many electrons are gained or lost in lithium? When an atom gains an electron does it become charged? Although either event is possible, a sodium atom is more likely to lose its single valence electron.

How are the electrons in magnesium arranged? When it becomes an ion, it loses 3 electrons, leaving behind only The chloride atom immediately becomes overbalanced negatively when it obtains the extra electron and this causes the atom to become a negative ion.

Electrons in the outer shell are known as valence electrons. The most reactive kind of metallic element is an alkali metal of group 1 e. A hydrogen atom does not form more than one covalent bond because it a has only one shell of electrons.

The atom which loses electrons becomes a positively charged ion or cation whereas the atom which gains electrons becomes a negatively charged ion or anion. Atoms consist of electrons, protons and neutrons. When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost or donated , the resulting ion is called cation. When electrons are gained, the resulting ion is called an anion.
