In their normal or neutral state, atoms have an equal number of positively charged protons and negatively charged electrons, and as a result, they have no net charge. Atoms can also gain or lose electrons, in which case the atom will have a net charge and will become an ion. For example, if a hydrogen atom loses its single electron, what it left is an ion with a charge of +1.
The ionized carboxyl group has a negatively charged oxygen atom bonded to a carbon atom, which is also bonded to a hydroxyl group. The ionized amino group has a positively charged nitrogen atom bonded to two hydrogen atoms.
When an atom is ionized, that means that it is sharing one or more electrons with another atom.
No. When you excite an atom, you just do something with the electrons within the atom. (You take them into higher energy levels.) An atom can be ionized only when it is charged, you would have to remove or add an electron. But you are only placing the electron on higher energy level, so it stays within the atom, therefore atom is not ionized.
Either one. You can have an ionized atom or an ionized molecule. Many ionized molecules are radicals that had been part of a larger molecule and the event that separated them also ionized the radical. This is what free radicalsare.

When an electron is removed from an atom, it is considered to be ionized. This results in the formation of a positively charged ion known as a cation, while the atom itself becomes positively charged.

Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized.
It must take electrons from either another atom or be ionized. If it takes electrons from another atom then it has more electrons than protons, which gives it a negative charge.

Ionized atom Excited atom
When an atom loses or gains electrons, it becomes ionized and can create a charged object when it interacts with other atoms. If an atom loses electrons, it becomes positively charged, and if it gains electrons, it becomes negatively charged. This imbalance of electrons between atoms creates an electric charge on the object.
No, the helium atom does not hold an overall charge. It consists of two protons in its nucleus, which are positively charged, and two electrons orbiting the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in a neutral atom.
