It forms an ion by giving away its only electron in the valence shell (3rd energy level).
The sodium atom becomes a singly positively charged cation, and the chlorine atom becomes a singly negatively charged anion.
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When an atom that has no charge loses two electrons, it becomes a positively charged ion, specifically a cation. The loss of negatively charged electrons results in an overall positive charge because the number of protons (which are positively charged) remains unchanged. For example, if a neutral atom of sodium (Na) loses two electrons, it becomes Na²⁺.
Sodium chloride is formed.
An atom becomes positive when it loses an electron, as electrons are negatively charged particles. When an atom loses an electron, it becomes a positively charged ion.
The sodium atom becomes a singly positively charged cation, and the chlorine atom becomes a singly negatively charged anion.
An example is what we call a salt - say solid crystalline sodium chloride - dissolved in water it becomes both types of ions: the sodium atom becomes a positively charged atom / ion while the chlorine atom becomes a negatively charged atom / ion.
ION haha apex is pretty boring huh
Sodium loses its one valence electron to become Na+
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
Na+
yes
In the ionic bond between sodium and chlorine in NaCl, one electron is transferred from the sodium atom to the chlorine atom. Sodium becomes positively charged and chlorine becomes negatively charged, forming the ionic bond.
When a sodium atom loses an electron, it becomes a positively charged sodium ion (Na+). This is because when an electron is lost, the number of protons in the nucleus of the atom is greater than the number of electrons, resulting in a net positive charge.
When a valence electron is transferred from a sodium atom to a chlorine atom, the sodium atom becomes a positively charged sodium ion (Na+) and the chlorine atom becomes a negatively charged chloride ion (Cl-). These ions form an ionic bond due to the attraction between the opposite charges.
ion that is positively charged
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
