The three main particles of an atom are: electron, proton, and neutron.
This table shows the differences on the three properties: location, charge, and mass, for the three particles:
particle location charge (C) mass (g)
electron space around the nucleus - 1.6 * 10^ -19 9.11 * 10^ -28
proton nucleus + 1.6 * 10^ -19 1.673 * 10 ^ - 24
neutron nucleus 0 1.675 * 10 ^ 24
It is important to drive some conclusions that permit you to have a better picture ot these particles and their differences:
1) electrons are in the space around the nucleus in regions called orbitals. Those are not orbits, because the electrons are not orbiting the nucleous.
2) Both protons and neutrons are inside the nucleus of the atom.
3) Electrons and protons have opposite charges of the same magnitude. The number of protons and electrons in an atom are equal, that is why they are neutral. The neutrons, which are inside the nucleus, with the protons, does not have charge.
4) The mass of the protons and the neutrons are almost equal.The difference does not count for the usual calculations.
5) The mass of one electron is 1 / 1840 times the mass of one proton. A very low quantity.
6) Electron is a fundamental particle (it is not formed by other particles).
7) Protons and neutrons are not fundamental particles. They are formed by quarks.
Answer:
Alfred Wegener
Explanation:
The drifting of tectonic plates is an on-going process that has changed the configuration of the continents since their formation in Archean time. This hypothesis first proposed in 1912 by Alfred Wegener, a German Meteorologist, was not widely accepted until after 1960.
Answer:
To be early to class or else they get harsh punishments
Explanation:
Europe by the influence of migration and the distinct ethnic groups of each country. ... World War II shaped the population patterns of Western Europe by its history, ... and ancient history that have shaped the sub-region's population patterns. ... The culture of ancient Rome still influences southern Europe.<span />
