The sum of all protons and neutrons - Apex Learning
What else can I help you with?
What is nearly all of an atoms mass made up of?
Nearly all of an atom and mass is made up of protons and neutrons.
What makes up nearly all of the atoms's mass?
The sum of all Protons and Neutrons.
Which part of an atom make up nearly all the mass of an atom?
This would be the NUCLEUS.
Where does majority of a atoms mass come from?
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.
Does a molecule have mass?
Yes. For example water molecules (2 hydrogen connected to 1 oxygen atom) have a bent shape.
What is ignored when determining relative mass of atoms?
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.
Contains nearly all the mass of the atom?
the nucleus
What is nearly all of an atom's made up of?
Nearly all of an atom and mass is made up of protons and neutrons.
The nucleus makes up 99 percent of the atoms what?
The nucleus makes up nearly all of the mass of an atom, with over 99% of its mass concentrated in the nucleus. Within the nucleus, most of the mass is found in the protons and neutrons, while the electrons surrounding the nucleus contribute very little to the overall mass.
John Dalton concluded that all the atoms of a single what have the same mass?
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
Lost of an atoms mass is in the nucleus?
Almost all of an atom's mass is in the nucleus.
Which two particles make up most of the mass of a hydrogen-2 atom?
The two particles that make up most of the mass of a hydrogen-2 atom are the proton and neutron. The proton has a positive charge and is responsible for defining the element, while the neutron has no charge and helps stabilize the nucleus.
