The general term is fairly straightforward, if you know a little Greek: polyatomic ions.
When the number of electrons and protons are not the same in an atom, it becomes an ion. An atom becomes positively charged if it loses electrons (more protons than electrons), and negatively charged if it gains electrons (more electrons than protons).
Ion. If the atom becomes more positive after the transfer of electrons, it is a cation. The metals in groups 1 and 2 are more likely to be cations. If the atom becomes more negative after the transfer of electrons, it is an anion. The halogens in group 6 and 7 are more likely to be anions.
Strictly speaking, there is more than one kind of large, positively charged subatomic particle, but the one that matters the most is the proton.
Protons are a type of subatomic particle, which are found in the nucleus of every atom. Protons have an electrical charge of +1. A proton is about 2000 times heavier than an electron.
An atom that has gained or lost an electron and is therefore no longer electrically neutral is generically called an ion.Specifically, an atom/ion that has lost one or more electrons (and is therefore positively charged) would be called a cationand an atom/ion that has gained one or more electrons (and is therefore negatively charged) would be called an anion.There is also a state of matter where all the electrons are stripped from atoms, this is called a plasma.The loss or gaining of an electron does not affect the number of protons in the nucleus.The number of protons and neutrons in the atom's nucleus are fixed for the atom from the moment of its creation unless it undergoes radioactive decay.For an atom, the number of protons determines what element the atom comprises and the variation in the number of neutrons forms the isotopes for that element.
A neutral atom could become a positively charged particle through the loss of one or more electrons. When an atom loses electrons, it becomes positively charged because there are more protons than electrons in the atom, creating an overall positive charge.
A cation is a positively charged particle formed by the loss of one or more electrons from an atom.
An atom that has gained an electron becomes a negatively charged particle called an anion. This occurs when the atom gains an extra electron and now has more electrons than protons, giving it a net negative charge.
Ion
A cation is an atom that has lost one or more electrons and thus became a positively charged particle.
an electron is a subatomic particle which every atom has. an ion is a charged particle (Ca2+ or Na+) It has one or more electrons than the number of protons...
An ion is formed when one or more valence electrons are transferred from one atom to another, resulting in a charged particle. The atom that loses electrons becomes positively charged (cation), while the atom that gains electrons becomes negatively charged (anion). This transfer of electrons creates electrostatic forces that hold the ions together in an ionic bond.
An atom can become positively charged by losing an electron, resulting in more protons than electrons. Conversely, an atom can become negatively charged by gaining an electron, which creates an excess of electrons compared to protons.
The number of electrons that surround the nucleus will determine whether or not an atom is electrically charged or electrically neutral. The amount of charge on a single proton is equal to the amount of charge possessed by a single electron. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. On the other hand, if an atom has an unequal number of protons and electrons, then the atom is electrically charged (and in fact, is then referred to as an ion rather than an atom). Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged. Conversely, any particle that contains more electrons than protons is said to be negatively charged.
When an atom is ionized, that means that it is sharing one or more electrons with another atom.
An Ion. An atom that loses electrons to become positively charged is a CATION. An atom that gains electrons to become negatively charged is an ANION. One there is an imbalanbced of electrons to protons, then it is is no longer and atom but an ion. An ATOM is a neutrally charged species An ION is a positively/negatively charged species.
When an atom has more protons than electrons it is called an ion. This is a positively charged particle because it has more protons than electrons, thus the positive charge takes over.
