nucleus....contains protons & neutrons
Silver and gold are made of atoms. Each atom contains protons, neutrons, and electrons.
All atoms have neutrons, protons and electrons.
Atoms are made of a nucleus, which contains subatomic particles called neutrons and protons, and electrons, which orbit the nucleus in certain areas.
Atoms that do not have any protons are called neutrons.
The Nucleus. Which is inside the electron clouds.
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons. But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes Definition of isotope: Atoms with same number of protons but different number of neutrons It shows that the different number of neutrons determines the existence of isotopes.

The nucleus of an atom contains protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus is the central core of an atom where most of its mass is concentrated.
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
Matter contains different types of atoms, which are composed of protons, neutrons, and electrons. These atoms can combine to form molecules and compounds.
Speaking very generally, most atoms consist of a dense nucleus which contains protons and neutrons, and an electron cloud away from the nucleus which contains electrons.
Protons, electrons, and neutrons are the three main parts of atoms. In an atom, the nucleus contains the protons and neutrons, the electrons are found in shells around the nucleus. On the periodic table, the atomic number tells you the number of protons of an element.
