Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All...
1 Atoms contain three different types of particle.These are electrons, neutrons and protons.(a) Which one of the three particles has a negative charge?(1)electron(s)(b) Which one of the three particles has the smallest mass?(1)electron(s)(c) Use words from the box to complete the ...
Protons and neutrons each weigh 1 atomic unit, while electrons are virtually weightless. Answer and Explanation: Two atoms with the same atomic number but different mass numbers are called b. isotopes To have the same atomic number, the...

Atoms:Atoms consist of tiny particles called protons, neutrons and electrons. Proton and neutrons are present in the nucleus and the electron resides around the nucleus. The protons number will be same as the electrons count in the atom. ...
2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period element above it?3.do some elements next to each other have the same number of neutrons?how is that possible?4.how are the colors ...
If an atom were about as big as a baseball stadium, the nucleus would be the size of a pea in the very center and the electrons would be somewhere on the outside edge.What makes an atom of gold different from an atom of iron is the number of protons, neutrons, and electrons inside...
