What did thompson contribute in forming the modern model of the atom?
JJ Thomson discovered that atoms were not indivisible because he discovered that atoms contained negatively charged subatomic particles which he called electrons.

Positively charged particles in an atom are called protons.
What energy of charged particles of atoms are called?
protons (:
The negatively charged particles in atoms are called?
Electrons
How many atoms are in atoms?
One! An atom is not made up of other atoms, but has a nucleus of a positively-charged proton and a neutrally-charged neutron. It is surrounded by a network of positively-charged particles called electrons. (sorry, NEGATIVELY charged particles called electrons!)
What is the number of positively-charged particles in an atoms called?
Protons
Who Discovered that atoms contain negatively charged particles called electrons?
In 1897, a British scientis named J.J. Thomson.
What is negatively charged particles of atoms with almost no mass called?
An Electron
What is a mixture of electrified fragments of atoms called?
fragments of atoms are the subatomic particles. the charged sub atomic particles are electrons and protons
