-1, since each electron has a charge of -1.
If an atom gains an electron, it will have a negative charge because electrons have a negative charge. The atom will now have more negatively charged electrons than positively charged protons, resulting in an overall negative charge.
There is no atom or element that has one proton, one neutron and ten electrons. Duterium has one proton, one neutron and one electron (in a neutral atom). Tritium has one proton, two neutrons and one electron (in a neutral atom), but that is the closest. In any neutral atom the number of electrons will equal the number of protons in the nucleus of that atom. An atom with one proton in its nucleus and 10 electrons just isn't possible.
You would get a positive ion, because there will be one extra positive charge no longer offset by the negative charge of that electron. You cannot take away a proton without changing the element, but you can add or remove valence electrons.
The electron has a negative charge and orbits the positively charged atomic nucleus. Many compounds are made possible by electron sharing between elements.
1) depends up on the the element basically: metals (electropositive elements) can donate nonmetals can(electro negative )elements can accpect the electrons 2)the result: if an atom losses the electron it becomes positively charged normally metals donate the electons and become + charged.
An atom has a postitive charge when it loses an electron and a negative when it gains one. It then becomes an ion through this process.
Atoms that have lost or gained one or more electrons are called ions.An atom that has gained and electron is an anion; and atom that has lost an electron is a cation. Gaining an electron means the anion has a negative charge; losing one or more electrons means the atom has a positive charge.
If one electron is gained, then it has a charge of -1.
An atom that gains an electron because negatively charge by one unit of elementary charge (1.602X10-19 coulombs) like F- as an atom that gains 2 electron will have 2 negative elementary charge
An atom that has gained or lost an electron becomes an ion. If an atom gains an electron, it becomes a negatively charged ion called an anion. If it loses an electron, it becomes a positively charged ion called a cation.
An ion. Eg Na atom loses one electron to become Na+
A chloride ion has gained one electron to achieve a full outer electron shell, giving it a negative charge. A chlorine atom is neutral and has one electron in its outer shell.
One electron
The chloride ion in salt has a charge of -1. It is derived from an atom of chlorine that has gained one electron to achieve a full outer electron shell, resulting in a negative charge.
If an atom gains an electron, it will have a negative charge because electrons have a negative charge. The atom will now have more negatively charged electrons than positively charged protons, resulting in an overall negative charge.
The formula for the bromide ion is Br-. It consists of one bromine atom that has gained one extra electron, giving it a 1- charge.
The Sodium atom with be positively charged [it will have a single positive charge]
