The nucleus
In the center of an atom is the nucleus, which contains protons and neutrons. Protons have a positive charge, neutrons are neutral; together they make up most of the atom's mass. Electrons orbit around the nucleus in distinct energy levels.
Nucleus
The part of the atom that contains neutrons and protons is called the nucleus.
protons and nuetrons are equal to no. of electrons present in atom
there are 12 protons in an atom of magnesium:-)
The centre of an atom is called the nucleus, and it contains only protons and NEUTRONSbut no electrons at all.
Neutrons and protons are located in the nucleus of an atom. The nucleus is the central part of an atom that contains most of its mass and is surrounded by electrons in the electron cloud.
In the nucleas
mass number = protons + nuetrons
Nucleus
The nucleus which contains the Protons and Neutrons.
Electrons, protons, and nuetrons. electrons are outside the nucleus, and protons and nuetrons are inside the nucleus.
