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 did Rutherford picture an atom as?
Rutherford pictured an atom as a small, dense, positively charged nucleus surrounded by orbiting electrons. He proposed this nuclear model based on his gold foil experiment, which showed that most of the atom's mass and positive charge is concentrated in the nucleus.
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 are the same about what can you say about the charge and mass of the nucleus of an atom?
The nucleus of an atom is positively charged due to the presence of protons, which carry a positive charge, while neutrons are neutral and do not contribute to the charge. The mass of the nucleus accounts for most of the atom's total mass, as protons and neutrons are significantly more massive than electrons. Together, these particles define the nucleus's overall charge and mass, making it dense and central to atomic structure.
What part of the atom was discovered by Rutherford?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
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 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 scientist showed that most of the mass and positive charge of an atom is concentrated in its center?
Ernest Rutherford demonstrated through his famous gold foil experiment that atoms have a dense, positively charged nucleus at their center. Most of the mass and positive charge of an atom is concentrated in this nucleus, with electrons orbiting around it.
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 are the characteristics of an atomic nucleus?
An atomic nucleus is composed of protons and neutrons bound together by the strong nuclear force. It is positively charged due to the protons it contains. The nucleus is extremely dense and makes up the majority of an atom's mass.
Which is more dense the nucleus or the electron cloud?
The nucleus is significantly more dense than the electron cloud. The nucleus contains most of the mass of an atom, while the electron cloud occupies a much larger volume with a very low density.
What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
What is an atom mostly?
Empty space makes up most of the atom which the negatively charged electrons use to orbit around the positively charged nucleus. The nucleus is made up of positively charged protons and neutral neutrons. The atom also has an electron cloud which is made up of, yes you guessed it, electrons
What is true of an atoms nucleus?
It contains Protons and Neutron's.
