What else can I help you with?
What are the basic unit of a chemical element called?
many identical atoms Answer is= Atoms.
What don't most hydrogen atoms contain?
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
Who said most of the mass is in tiny dense charged nucleus?
The concept that most of an atom's mass is concentrated in a tiny, dense, positively charged nucleus was primarily established by Ernest Rutherford through his gold foil experiment in 1909. Rutherford's findings demonstrated that atoms consist of a small nucleus surrounded by electrons, leading to the understanding of the nuclear structure of atoms. This was a pivotal moment in the development of atomic theory, reshaping our understanding of atomic structure.
What are the particles of mercury?
The particles of mercury are called atoms of mercury. Mercury atoms consist of a nucleus composed of protons and neutrons, surrounded by a cloud of electrons in various energy levels or shells.
Can a atom divide into smaller particles?
Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Atoms can undergo nuclear reactions, such as fission or fusion, which can split the nucleus into smaller particles. However, in normal chemical reactions, atoms do not divide into smaller particles.
What are the composition of atoms?
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.

What is the most of the mass of an atoms?
The nucleus.
What does most of the atoms mass come from?
the nucleus
Where is most of an atoms mass?
Inside the nucleus.
What two things make up matter?
Matter is composed of atoms, which are the smallest units of matter. Atoms consist of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons.
Every object around you is made up of?
atoms, which are the basic building blocks of matter. Atoms consist of a nucleus, containing protons and neutrons, surrounded by electrons. Different arrangements and combinations of these atoms determine the properties and characteristics of the objects around us.

Most atoms are composed of electrons protons and neutrons. Which particles are found in the nucleus of a gold atom?
Not just "most" atoms , but all atoms are composed of protons and neutrons, which are found in the nucleus, and electrons surrounding the nucleus in the electron cloud. And these atoms include gold.
