Nucleus
nucleus the nucleus contains protons (positive) and neutrons (neutral). The nucleus is always the positively charged, dense center of an atom.
There is a dense, positively charged mass in the center of an atom...
The positively charged center of an atom is the nucleus. The nucleus contains the protons and the neutrons. The protons are positively charged and the neutrons have no charge, therefore the nucleus is positively charged.
Rutherford pictured the atom as a dense positively charged nucleus at the center, surrounded by orbiting negatively charged electrons. This model, known as the nuclear model, revolutionized our understanding of the structure of the atom.

The positively charged center of an atom is called the nucleus. It contains protons and neutrons, surrounded by a cloud of negatively charged electrons that orbit the nucleus in specific energy levels.
The gold foil experiment supported the statement that atoms have a small, positively charged nucleus at their center. This overturned the previous "plum pudding" model of the atom, where positive charge was thought to be spread throughout the atom.
For starters, All atoms have a positive charge. Protons are positive, neutrons are neutral and the electrons are negative. Only the protons and neutrons are in the center making the center positive. The center is the nucleus.
