Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
The charge of a nitrogen ion (N) can vary depending on the number of electrons it has gained or lost. Typically, a nitrogen ion can have a charge of -3 when it gains three electrons or +3 when it loses three electrons.
A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
An oxygen atom has 6 protons and 6 electrons, giving it a neutral charge. When it gains 2 electrons to form an oxygen ion, it will have 8 electrons in total. Since it now has 2 more negatively charged electrons than positively charged protons, the oxygen ion will have a charge of -2.
The resulting oxygen ion has a charge of -2.
An atom that gains three electrons will become an ion with a 3- charge.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
an ion
Electrons have a negative charge. Therefore, an atom having extra electrons is a negative ion.
The charge of a nitrogen ion (N) can vary depending on the number of electrons it has gained or lost. Typically, a nitrogen ion can have a charge of -3 when it gains three electrons or +3 when it loses three electrons.
It is called an ion.
electric charge
If an atom gains an electron it has a net negative charge and is known as an anion. A ion has a single atom which is atomic or monatomic.
A positive ion can become a neutral atom by gaining electrons. When a positive ion gains one or more electrons, it becomes neutral because the negative charge of the electron(s) cancels out the positive charge of the ion.
An oxygen atom has 6 protons and 6 electrons, giving it a neutral charge. When it gains 2 electrons to form an oxygen ion, it will have 8 electrons in total. Since it now has 2 more negatively charged electrons than positively charged protons, the oxygen ion will have a charge of -2.
The ion given is formed when the neutral arsenic atom gains three electrons.
The resulting oxygen ion has a charge of -2.
