An ion with a negative charge is known as an 'ANION'.
Examples are ;- Cl^(-) , O^(2-) , N^(3-)
NB An ion with a positive charge is a 'CATION'.
Examples are ;- K^(+) , Mg^(2+) , Al^(3+).
Collectively, anions and cations are known as 'ions'.
NNB When an atom loses or gains electrons, to become a charged species, it is no longer an atom, but an ION.
negative one
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
An ion does have a charge. That is what makes it an ion.
The negative charge for bicarbonate (HCO3-) is one.
SO4 -----> 2- (negative 2)
A negative charge is the opposite of an ion. An Ion with a negative charge becomes an Anion. Normally with a negative charge they are called Electrons. See electrons for more help
A charge which is not a positive charge is a negative charge.
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
An ion is an atom with a positive or negative charge.
Yes, there is a limit to negative charge that can occur on an ion.
The charge for the bicarbonate ion (HCO3-) is -1.
negative one
The hydroxide ion, OH-, has a negative charge of 1-.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
An ion does have a charge. That is what makes it an ion.
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
