Rutherford
Positive atoms: cations. Negative atoms: anions
The answer is in the names of the particles. The Neutron is neutral. The Electron is negative. The Proton is positive.
a zewithalarion shows poth positive and negative; go figure...
negative,positive,none
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.
Atoms become positive ions when they lose an electron in a reaction. An electron is negative and a proton is positive, so when the atom loses an electron it will have more positive than negative, and the atom will be a positive ion. The atoms at the left of the periodic table usually lose electrons in reactions.
Positive ions
positive: proton negative: electron neutral: neutron
