negative
Negative
This atom become a cation (positive).
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative charge.
An atom with an additional electron has a negative charge. By gaining an electron, the atom has more negatively charged particles (electrons) than positively charged particles (protons), resulting in an overall negative charge.
Well an electron is negative so negative i guess But The atom is always neutral because the number of protons = electons
Sodium become a cation (positive charge) - Na+.
neutral
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-).
An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with 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 electron is the part of the atom that has a negative charge. It orbits the nucleus, which consists of positively charged protons and neutrally charged neutrons.
when an electron is added to an atom, the atom will acquire a negative charge.
