how does an ion form from an atom?

Question

explain this please

Answer 1

A lot of elements dont have their outer level of electrons filled so they want to either lose or gain electrons. When an element gains or loses an electron and its total count of electrons changes, it is called an ion.

Answer 2

From Norrie.me

Ionisation of an element is caused by the gain or loss of Electrons. A neutral atom has an equal number of Protons (+), and Electrons (-).
*...If Electrons are LOST, there will be more Protons in the atom than Electrons. The Atom will now have a Positive (+) charge and is a 'Cation'. (Goes to the Cathode)
*...If Electrons are GAINED, the number of Electrons (-) will be greater than the number of Protons (+). The Atom will now have a Negative (-) charge and is an 'Anion'. (Goes to the Anode).

Answer 3

An ion is formed when a neutral atom (one with the same number of protons and electrons) gains or loses an electron. When it does so, it ceases to be neutral, and now has a net electric charge.

Answer 4

Whenever an atom is bombarded (or struck) by a high energy photon or other particle (say from ultraviolet, x-ray, or gamma-ray radiation, for example), it can lose one of its orbiting electrons. Sometimes it can lose more than one of its electrons. For instance, astronomers can see singly- and doubly-ionized oxygen atoms in some nebulae. Nature always seems to strike a balance, therefore most atoms have a net neutral electrical charge, but in the case of ionized atoms, this isn't always so. An ionized atom can have a net electrical charge, which would be either positive or negative, of course. Ionized atoms are somewhat common in chemistry, as even something as everyday as soaps are based upon their properties. Hope this helps...

Answer 5

An ion is formed when an atom either looses or gains an electron that rotates around a nucleus.

Answer 6

an ion is a charged atom to becom charged it needs to gain or lose electrons which have a negative charge. They gain and lose electrons with other atoms. for example if an atom lost one electron it is now an ion with a positive charge.

Answer 7

Monatomic ions are formed by using the addition of electrons to the valence shell of the atom, or the dropping of electrons from this shell. the internal shells of an atom are crammed with electrons that are tightly absolute to the certainly-charged atomic nucleus, and so do no longer take part in this manner of chemical interplay. the approach of gaining or dropping electrons from a independent atom or molecule is named ionization.

Answer 8

From: Answers.com

Ion (it is an atom)

An atom or group of atoms that bears an electric charge. Positively charged ions are called cations, and negatively charged ions are called anions. When a single atom gains or loses an electron, monoatomic ions are formed. For example, reaction of the element sodium (Na) with the element chlorine (Cl) leads to the transfer of electrons from Na to Cl to form Na+ cations and Cl− anions. In general, atoms of metallic elements (on the left side of the periodic table) lose electrons to form cations, while atoms of nonmetallic atoms (on the right side of the periodic table) gain electrons to form anions. Ions can bear multiple charges, as in the magnesium ion (Mg2+) or the nitride ion (N3−). The charge on monoatomic ions is usually the same for elements in the same column of the periodic table; for example, hydrogen (H), sodium, lithium (Li), potassium (K), rubidium (Rb), and cesium (Cs) all form +1 ions. See also Periodic table.

Ions can also comprise more than one atom and are then called polyatomic ions. For example, the ammonium ion (NH4+) carries a positive charge and is composed of one nitrogen atom and four hydrogen atoms. The nitrate ion (NO3−) is composed of one nitrogen atom and three oxygen atoms and carries a single negative charge. Polyatomic ions are usually depicted inside brackets with superscripted charges, as shown in the structure below.

Answer 9

When an electron gets kicked out or when the atom gains an electron (generally to fill its outer ring).

Answer 10

an atom is neutral. it does not have a positive or negative charge. when an atom becomes an ion, it has more electrons or less electrons than normal. you know which because electrons are negative.

so if something has a + charge, it is missing an electron because it lost a negative charge. if something has a - charge, it has an extra electron because it has an additional negative charge.
