Gaining electrons will increase the negative charge of an ion, making it more negative. Losing electrons will decrease the negative charge of an ion, making it more positive. The overall charge of an ion is determined by the number of protons in the nucleus compared to the number of electrons.
Na is positive ion,Cl is negative ion
A negative ion is called an anion, while a positive ion is called a cation.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
Some are and some are not. One negative ion, the chloride ion, is generally harmless. Another negative ion, the cyanide ion, is highly toxic.
A negative ion is formed by the addition of negatively charged electrons. The protons do not change.
Gaining electrons will increase the negative charge of an ion, making it more negative. Losing electrons will decrease the negative charge of an ion, making it more positive. The overall charge of an ion is determined by the number of protons in the nucleus compared to the number of electrons.
The charge of a fluoride ion is -1, as it gains one electron to achieve a stable electron configuration following the octet rule.
Na is positive ion,Cl is negative ion
Chlorine has 7 electrons in its valence shell, and to fill the octet rule, it needs one more. So it will accept one electron to form the Cl- ion. Sulfur has 6 valence electrons, and to fill the octet rule, it needs 2 more electrons. So it will accept 2 electrons to form the S-2 ion.
A positive ion is an ion with no negative charges.
Anion. It gains an electron, making it negative.
It will be a negative ion, or in other words, a anion.
Fluorine is negative and will produce a negative ion.
The negative ion for iron(III) phosphate is PO4^3- called phosphate ion.
A negative ion is called an anion, while a positive ion is called a cation.
When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.
