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.
One or more electrons from the outer shell
Electrons
If electrons are lost - cations are formed
If electrons are gained - anions are formed
Valence electrons
Photons always behave somewhat like waves and somewhat like particles. We think of these as being basically different types of things, but on the subatomic scale, they blend into each other, and the distinction is lost.
no
Mass is never lost nor gained - neither in chemical reactions, nor in other cases.
As heat is a form of energy, it isn't lost or gained, it's just converted into another form of energy.
quantum
They are gained.
In a redox reaction the number of electrons lost by one particle is equal to the number of electrons gained by another particle.
an ion.
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
An ion is an atom or group of atoms that has an electrical charge from having either gained or lost electrons. An ion may have either a positive or a negative charge. An electron is a subatomic particle that carries a negative charge and is usually found in the orbitals of atoms and ions.
False -it is the electrons not the protons.
An electron is the subatomic particle that has a negative charge.A proton has a positive charge and neutron has a neutral charge.These three together form all known particles (except hydrogen, that doesn't normally have a neutron). The protons and neutrons form the nuclie. The electrons form shells around it, they are held in place by there attration to the protons. Ions are atoms that have lost or gained electrons. e.g.[Zn]+1is a zinc alom that has gaind an electron.
No. All of the elements, and their amounts will be present in the product/s, but they will be arranged differently.2Na + Cl2 --> 2NaClIn the balanced equation for the synthesis of sodium chloride (NaCl), the amount of sodium (Na) and chlorine (Cl) is the same on both sides.
An atom is the smallest particle of a chemical element that retains its chemical properties. A molecule is the smallest amount of a substance that consists of a number of atoms of the same or of different elements.
No. Matter can neither be created or destroyed in normal circumstances. The exceptions to this are during radioactive decay, in the core of a star or in a particle accelerator ,
Charlie gained independence, but he lost Mrs.Kinnian
when a negative ion forms electrons are gained and energy is given off and when a positive ion forms electrons are lost and energy is used.
