Atoms become negatively charged when they gain an electron.
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
Some are and some are not. One negative ion, the chloride ion, is generally harmless. Another negative ion, the cyanide ion, is highly toxic.
An electron is added in an atom to form a negative ion or anion. Because electron carry negative charge.
A positive ion and a negative ion.
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.
Chlorine can form both positive and negative ions. As an element, chlorine typically forms a negative ion (Cl^-) by gaining one electron to achieve a stable electron configuration. However, in certain compounds, chlorine can also form a positive ion (Cl^+) by losing an electron.
if a substance loses one or more electrons it becomes positively charged and when it gains an electron it becomes negatively charged
Chlorine would form a negative ion and the other three positive ions.
Fluorine is negative and will produce a negative ion.
N and P for example. Nitrogen will form a N3- the nitride ion.
A negative ion forms when an atom gains one or more extra electrons, resulting in an overall negative charge. This can occur through processes like electron transfer or interaction with other charged particles.
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
