The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.
The sum of all Protons and Neutrons.
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
Water has measurable mass because it is composed of molecules, which are made up of atoms. These atoms have mass, and when they come together to form a water molecule, that mass adds up. The total mass of water is a measure of the sum of all the masses of its individual molecules.
Both matter and atoms have mass and occupy space. Matter is made up of atoms, which are the basic building blocks of all matter. Both matter and atoms exhibit different physical and chemical properties based on their composition and arrangement.
The total mass remain constant after a chemical reaction.
When determining the relative mass of atoms, the mass of electrons is typically ignored. This is because electrons are much less massive than protons and neutrons, contributing negligibly to the overall atomic mass. Instead, the relative atomic mass primarily considers the masses of protons and neutrons, which reside in the nucleus and account for nearly all of the atom's mass.
Nearly all the mass is in the nucleus; however, the bulk of an atom's volume is empty space.
