Protons and neutrons have a relative mass of one, electrons have a relative mass of 1/2000
The atom is about 10,000 times as big as the nucleus.
If a penny was the size of the United States, an atom would be about the size of a grain of salt. Atoms are incredibly small, with a diameter of about 0.1 to 0.5 nanometers, compared to the much larger size of everyday objects like coins.
The empirically measured covalent radius of carbon is 7o picometers; it is a small atom.
An atom of Indium has an atomic radius of about 155pm (picometers).
The atom was first split in a laboratory at University of Chicago in 1938.
The electron.
Because you have more body parts in your abdomen.
The atom is about 10,000 times as big as the nucleus.
The nucleus of an atom is very small compared to the overall size of the atom. It contains protons and neutrons, which make up almost all of the atom's mass, but occupy a tiny fraction of its volume. The rest of the atom is mostly empty space where electrons move around.
Well, Aristotle was a big philosopher, and he basically told everyone that the idea of this atom was a big misunderstanding and couldn't possibly be true. Being as respected as he was, people listened to him and sort of blew off this whole atom idea, until the 1800's, when Dalton proposed his atomic theory.
Big
no
The radius of a sulfur atom is 106 picometers.
Melbourne is a city, South Africa is a whole country! Melbourne is about the same size as Cape Town (in South Africa)
Small and big are comparative terms. It is big compared to a village, small compared to London.
It can be amended if there are a few parts that need to be corrected. However you can't take out a whole big section like freedom of speech.
No, it came into our atmosphere whole soo unless it was part of the big bang theory it was not divided into two.
