a. What is an atom electrically neutral? b. What is sub - atomic particles of an atom? c. Who found the atomic model? d. Name the shells of an atom? e. What are charges present in proton, electron and newton.
Answers
A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of theatom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
John Dalton was the first to adaptDemocritus' theory into the first modern atomic model. J.J Thomsonwas a physicist who is credited for discovering the electron. He used his research on cathode ray tube technology in this discovery.
Explanation:
Atomic Particles
Atoms consist of three basic particles:protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain theelectrons (negatively charged).
Answer:
If an atom contains equal numbers of protons and electrons then the atom is electrically neutral.
Sub atomics particles are smaller then atoms.
John Doltan founded the first atomic model.
The electrons shells are labelled K ,L ,M, N, O, P and Q or 1, 2, 3, 4, 5, 6 and 7 ; going from innermost shells outwards. Electrons in outer shells have higher average energy and travel further from the nucleus than those inner shells.
The charges present in proton is - Positive
electron is - Negative
newton is - Negative or Negative integers.
I think instead of newton it should be neutrons ; neutrons have - no charge .
