Because atoms like to have a full outer shell - a sodium (1+) ion previously had 1 electron in it's outer shell, but it loses a (negatively charged) electron to gain a +1 charge.
Chlorine, however, usually has 7 electrons in it's outer shell, but it gains a (negatively charged) electron to gain a -1 charge.
Remember;
gaining electrons = negative ions
losing electrons=positive ions
What else can I help you with?
Why is the chlorine ion attracked to the sodium ion?
When elements first come together they are both electrically neutral. When they get close enough, an electron transfers from the sodium to the chlorine. This makes the a positive sodium ion, Na+, and a negative chlorine ion, Cl-.
After Chlorine accepts the electron from sodium what is its charge?
After chlorine accepts the electron from sodium, it becomes a chloride ion with a negative charge of -1.
What charge does sodium and chlorine become after reacting together?
Sodium becomes a positively charged ion (Na+) and chlorine becomes a negatively charged ion (Cl-) after reacting together to form sodium chloride (NaCl).
What would happen if 1 ion of chlorine combined with 1 ion of sodium?
When 1 ion of chlorine combines with 1 ion of sodium, they form a molecule of sodium chloride (table salt). The chlorine ion gains an electron from the sodium ion, creating a stable compound with a balanced charge.
What kind of bonds forms between sodium and chlorine?
Ionic bonds form between sodium and chlorine. Sodium will donate its outer electron to chlorine, resulting in the formation of a sodium ion with a +1 charge and a chloride ion with a -1 charge. These ions are held together by strong electrostatic attractions.

What are the charges on the sodium ion and chloride ion after they combine?
When sodium and chloride ions combine to form sodium chloride (table salt), the sodium ion carries a positive 1 charge, and the chloride ion carries a negative 1 charge. The charges balance out in a one-to-one ratio, resulting in a neutral compound.
What charge does sodium and chlorine become after reacting together?
Sodium becomes a positively charged ion (Na+) and chlorine becomes a negatively charged ion (Cl-) after reacting together to form sodium chloride (NaCl).

When 1 ion of chlorine combines with 1 ion of sodium, they form a molecule of sodium chloride (table salt). The chlorine ion gains an electron from the sodium ion, creating a stable compound with a balanced charge.
Why can one sodium ion bond with one chlorine ion?
Sodium ion has one electron to give, and chlorine ion needs one electron to fill its outer shell. Through ionic bonding, sodium donates its electron to chlorine, forming a stable sodium chloride molecule.
What kind of bonds forms between sodium and chlorine?
Ionic bonds form between sodium and chlorine. Sodium will donate its outer electron to chlorine, resulting in the formation of a sodium ion with a +1 charge and a chloride ion with a -1 charge. These ions are held together by strong electrostatic attractions.
What ions are in NaCl?
A sodium ion. Cation. Na+ A chlorine ion. Anion Cl- Forms NaCl, sodium chloride.
What atoms does the compound NaCl contain?
The compound NaCl contains sodium (Na) and chlorine (Cl) atoms. Sodium contributes one positively charged ion (Na+) and chlorine contributes one negatively charged ion (Cl-) in the ionic compound sodium chloride (NaCl).
What happens when sodium ions is attracted to a chlorine ion?
forms a covalent bond APEX:They form an ionic compound.
Predict the charge that an ion of sodium would have?
I predict that an ion of sodium will have a charge of plus one.
What are the ions for sodium and chlorine?
The sodium ion is Na+, while the chloride ion is Cl-.
