Who first Proposed the idea that atoms had positive and negative parts?
The idea that atoms had positive and negative parts was first proposed by J.J. Thomson in the late 19th century through his "plum pudding" model of the atom. Thomson suggested that atoms were composed of positive and negative charges distributed throughout a neutral sphere, like plums in a pudding.
What positively charged parts of atoms?
The answer is in the names of the particles. The Neutron is neutral. The Electron is negative. The Proton is positive.
What is an atom that has a net positive or negative electric charge?
Positive atoms: cations. Negative atoms: anions
What are atoms OR groups of atoms with a positive OR negative charge?
a zewithalarion shows poth positive and negative; go figure...
What parts of the calcium chloride are attracted to what parts of the water molecule?
The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.
Particles in atoms can be?
negative,positive,none
What describes atoms that have a positive and negative end?
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.
Do atoms have a higher number of positive charges or negative?
Normally atoms are neutral.
If a proton is negative and a neutron is positive when they come together equally how can there be positive and negative atoms?
Loss or gain of electrons.
Can atoms have positive or negative charge?
Yes, if they are ions
Atoms with a positive or negative charge are called ions?
That's correct! When atoms gain or lose electrons, they become ions with an overall positive or negative charge. Positive ions are called cations, and negative ions are called anions.
What is a group of atoms with with a positive or negative charge?
A polyatomic ion is a group of atoms with a charge.
