Small positive ion,
Mid elemental atom,
Large negative ion.
Positive ions
Positive atoms: cations. Negative atoms: anions
a zewithalarion shows poth positive and negative; go figure...
Isotopes are just the different possible nuclear weights of each element. Some are stable; some are unstable and radioactive. Since all atoms are isotopes and all isotopes are atoms, Isotopes can - and do - form ions, consequently they can have positive and negative charges.
yes
negative,positive,none
Atoms consist of electrons (negative charge), protons (positive charge), and neutrons (neutral charge), while molecules consist of atoms.
Compound made of ions, which are atoms of an element with more or less electrons than number of protons, giving them a positive or negative charge.
Normally atoms are neutral.
Atoms do not have positive and negative ends.Molecules, which are made up of several atoms, can be positive at one end and negative at the other; these are called "polar" molecules. The most common polar molecule is water, made up of two hydrogen atoms and one oxygen atom; H2O.
Yes, if they are ions
Loss or gain of electrons.
