Negative
When an atom gains or loses electrons, it is trying establish a more stable situation in which it has a full valence shell. An atom that has gained or lost valence electrons is called an ion. When a positive ion and a negative ion can bond due to their opposite charges. This is called an ionic bond.
An atom that has gained an electron becomes a negatively charged ion.
An atom that has gained or lost electrons is called an ion. An atom that has gained one or more electrons becomes a negatively charged ion called an anion. An atom that has lost one or more electrons becomes a positively charged ion called a cation.
They are gained.
An ion
An ion.
To make a positive ion, we need to remove one or more of the negative components from an atom. The negative charges that make up an atom are the electrons, which can be found in shells or orbitals some distance from the nucleus. Take away one or more electrons, and the protons, the positive charges that make up atoms and which hang out in the nucleus, give the atom an overall positive charge. An atom that has lost one or more electrons becomes a positive ion.
an ion
Yes. An atom that has gained one or more electrons is a negatively charged ion called an anion, and an atom that has lost one or more electrons is a positively charged ion called a cation.
An atom with no electric charge will be called a neutral atom. In a neutral atom, there is a balance of charges, and the number of protons will be equal to the number of electrons. It's really that simple. Compare this to atoms that have an imbalance of charges. These atoms are called ions.
A negatively charged ion is an atom that has gained one or more electrons and has therefore gained a negative charge.
An ion is a charged atom that has gained or lost one or more electrons. An ion has an unequal number electrons and protons giving it either a positive or negative charge.
