Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.
The nucleus of an atom represents most of an atom's mass.
Nothing. The question is wrongly stated. Each single atom is an element.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.

The smallest particle that represents an element is an atom. Atoms are made up of protons, neutrons, and electrons, which are the basic building blocks of matter in the universe.
Dalton's mental image of an atom can be best represented by a solid, indivisible sphere with no internal structure, similar to a billiard ball. This model suggested that atoms were the smallest, fundamental particles of matter.
The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
A plum pudding model with negatively charged electrons embedded in a positively charged sphere.
The nucleus of an atom represents most of an atom's mass.
thomas discovered that the atom contained smaller particals called electrons

The formula for water is H2O, where "H" represents one atom of hydrogen and "O" represents one atom of oxygen.
Nothing. The question is wrongly stated. Each single atom is an element.
A silver halide--a compound consisting of a silver atom bonded to either an iodine atom or a chlorine atom.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.

The atomic symbol in a Lewis structure represents the nucleus of an atom, typically denoted by a letter. It does not include any electrons. The letter serves to identify the element that the atom represents.
