To answer this question let me just explain ions. If an atom loses an electron, it becomes a positive ion.
Example- Oxygen atom loses an electron so now it has 7, O+
If it gains an electron it becomes a negative ion.
Example- O-
The reason this happens is because when it loses one, there is not enough negative charge to balance with the protons ( + ). Therefore it becomes positively charged. visa-versa
The sodium atom becomes a positive ion (Na+) when it loses a valence electron, and the chlorine atom becomes a negative ion (Cl-) when it gains a valence electron. This transfer of electrons creates an ionic bond between them, forming sodium chloride (NaCl), or table salt.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
In the Lewis dot structure for NaCl showing an ionic bond, sodium (Na) will have one dot representing its single valence electron, and chlorine (Cl) will have seven dots, one for each of its seven valence electrons. The electrons will be shown transferring from sodium to chlorine to form an ionic bond, with sodium losing its electron to become a cation (Na+) and chlorine gaining an electron to become an anion (Cl-).
positively
Yes, electrons are transferred from sodium atoms to chlorine atoms to form ionic bonds. Sodium atoms lose one electron to become positively charged sodium ions, while chlorine atoms gain one electron to become negatively charged chloride ions. This transfer creates an electrostatic attraction that holds the ions together in an ionic compound.
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 .

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.
A negatively charged "ion".
The sodium atom becomes a positive ion (Na+) when it loses a valence electron, and the chlorine atom becomes a negative ion (Cl-) when it gains a valence electron. This transfer of electrons creates an ionic bond between them, forming sodium chloride (NaCl), or table salt.
If a chlorine atom gains a valence electron, it becomes a negatively charged ion known as a chloride ion (Cl⁻). Conversely, if it were to lose a valence electron, which is less common for chlorine, it would become a positively charged ion, but this scenario is unlikely due to its high electronegativity. Thus, the most common ion formed by chlorine is Cl⁻ when it gains an electron.
Sodiumbeing in group 1 needs to loose 1e- to become stable. Chlorine being from group 17 needs to gain 1e- to become stable. Sodium gives its extra electronto the chlorine atom. Now both have 8 electrons in their valence and are stable. The sodium gets a positive charge because it lost and electron. The chlorine gets a negative charge because it gained an electron.This creates an ionic bond
Sodium becomes a cation and chlorine becomes an anion.
sodium becomes positive ( as it loses a negative electron but still hs the same number of + protons) with a single + charge. chlorine becomes negative ( as it gains an extra negative electron but still hs the same number of + protons) with a single - charge. NaCl -------> Na+ Cl-
Chlorine needs one additional valence electron to have a full valence shell, as it has seven valence electrons in its outermost shell and aims to have a complete octet with eight electrons for stability.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
