It is continuous and not made of discrete particles

It is made of indivisible particles

It can be subdivided into small, whole number ratios

It is made of negatively charged particles

All alike

Different from the atoms of all other elements

Made of positively charged material with embedded electrons

Continuously divisible

There are two forms of electrical charge - positive and negative

Opposite charges attract each other

Like charges repel each other

All of the above

Atoms are spheres of positively charged material with embedded electrons

Atoms consist of a massive, positively charged center surrounded by a flat ring of electrons

Atoms have hooks to hold them together and are slippery

Atoms are made up of a tiny, dense, positively charged central nucleus surrounded by negatively charged electrons

In the nucleus

In the orbitals

In the energy levels

In the positively charged material with embedded electrons
