What is a nucleus in a atom?
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.
What is true of an atom nucleus It is negatively charged and takes up most of the atom and space. It is negatively charged and includes most of the atom and mass. It is positively char?
It is positively charged and includes most of the atom and mass.
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
What is todays atom model?
Scientists think that atoms basically look like an electron cloud circling a small, very dense nucleus. The electron cloud is negatively charged, makes up most of the volume of the atom, and has hardly any mass, but the nucleus is positively charged, very small, and contains all of the mass of the atom.
What did Rutherford gold foil experiment suggest about the structure of an atom?
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
Who was the first to propose that most of the mass of an atom is in the tiny dense positively charged nucleus?
Greek philosopher Democritus.

What is the most dense part of an atom?
The nucleus is the most dense part of an atom.
What are the characteristics of nucleus of atom?
The nucleus is made up of neutrons and protons (called nucleons) held together by the strong nuclear force. It is overall positively charged and makes up most of the mass of the atom yet accounts for hardly any space at all. This is because it is small and very dense.
Where are protons found in the nucleus of an atom?
Protons, and neutrons make up the nucleus of an atom. The nucleus is the centre of an atom where most of the mass is found. Protons are positively charged, neutrons have no charge.
What is true of an atoms nucleus?
It contains Protons and Neutron's.
The center of an atom where the neutrons and protons exist?
That is called the nucleus. It is positively charged and it makes up most of the atom's mass.
