A chlorine atom gains an electron to become a chloride ion. This extra electron gives the ion a negative charge, balancing the positive charge of the proton in the nucleus, resulting in a stable electron configuration.
chlorine atom will first convert to the gaseous chlorine atom which will then add one electron to form chloride ion.
When an electron is transferred from a sodium atom to a chlorine atom, the chlorine atom becomes a negatively charged ion because it gains one electron. This negatively charged ion is known as chloride ion.
A chloride ion is slightly larger than a chlorine atom, because in an ion there is one more electron than proton, allowing the electron shells to expand slightly. In a chlorine atom, the number of electrons and protons is the same.
A negatively charged atom of chlorine is called a chloride ion.
Chlorine is an atom with a neutral charge, 0. Chloride is the chlorine ion with a charge of -1. You can tell the two apart because the chlorine atom is simply "Cl" whereas the chloride ion is denoted "Cl" with a superscript minus sign.

The radial size of the chloride anion is bigger. Because, with the same number of protons , but one extra electron, the attractive pulling power towards the nucleus is less, so this allows the ion to be bigger. Also trying to 'squeeze in ' an extra electron , there is some 'steric hindrance' , so the electrons have to 'shove-up' to allow in the extra electron. Radial diameter of chlorine atom is 102 Angstrom /pm (picometres) Radial diameter of chloride anion is 181 Angstrom /pm (picometres)

The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.

Actually, when sodium forms an ionic bond with chlorine, the sodium atom donates one electron to chlorine, resulting in the formation of a positive sodium ion and a negative chloride ion. The sodium ion becomes Na+ and the chloride ion becomes Cl-.
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.
' cl- ' is nothing. . It does not mean a thing. However, if you mean ' Cl^(-) ' or 'Cl-' Then it is NOT an atom . It is an ION, and more correctly an 'ANION'. NB For ALL chemical elemental symbols the first letter is ALWAYS a CAPITAL letter. Hence 'Cl/Cl^(-)' not 'cl-'. NB An atom is a neutrally charged species. The number of protons is balanced by the same number of electrons. An ion carries a positive/negative charge. The number of electrons differed from the number of protons. So ' Cl ' is an ATOM , but ' Cl^(-) ' is an ION . Any atom that carries a charge is no longer an atom but an ion. Positively charged ions are named 'CATIONS'. Negatively charged ions are named ' ANIONS'.
The chlorine ion is in group 7 so it has a charge of -1.
when sodium valence electron is transferred to chlorine , both atoms become ions . the sodium atom becomes a positive ion . the chlorine atom becomes a negative ion .
