Charge of an atom that has gained electrons?
It is a negative charge
What is an atom that has given up or gained electrons?
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.
Is a positive ion an atom that has gained an electron?
NO!!!!! A positively charged ion has IONISED/LOST electrons. e.g. Sodium atom has 11(+) protons and 11(-) electrons Hence 11 +11 - = 0 a neutrally chartged atom. However, when sodium is ionised , loses one electron The sodium atom is now 11(+) protons and 10(-) electrons. Hence 11+10- = 1(+) a positively charged ion. It is symbolised by ' Na^(+) '. Similarly for other positively charged ions, known as CATIONS. e.g. Ca^(2+) or Al^(3+). An ion that has gained electrons is known as an ANION , and it has undergone 'Electron Affinity'. e.g. Chlorine atom has 17(+) protons and 17(-) electrons Hence 17 +17 - = 0 a neutrally charged atom. However, when chlorine undergoes electron affinity , gains one electron The chlorine atom is now 17(+) protons and 18(-) electrons. Hence 17+18- = 1(-) a negatively charged ion. It is symbolised by ' Cl^(-) '. Similarly for other negatively charged ions, known as ANIONS. e.g. O^(2-) or N^(3-).
When an atom in no longer neutral it exists with a charge an atom that has a charge is called a?
An ION A positively charged (+) ion is named a CATION A negatively charged (-) ion is named an ANION . NB Once an atoms gains/loses electrons, and becomes a charged species, it is NO longer an atom, but an ION.
When an atom becomes an ion with a negative 2 charge the atom?
Gained 2 electrons
An atom that has gained an electron is?
An atom that has gained an electron becomes a negatively charged ion.
What is the name of any atom or group of atoms with a negative charge?
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
What difference between atom and ion?
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
What are differences between atom and ion?
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
When a atom has a positive or negative charge beause it lost or gained an electron is a?
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.
What is an atom that has lost or gained an electron and now carries a positive or negative charge called?
I believe the answer your looking for in an Ion.An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
Is cl- an atom?
No, Cl- is not an atom. It is an ion. Cl- represents a chlorine atom that has gained an electron, giving it a negative charge.
