What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
Why does not an atom of an element represent the actual mass of its atom?
An atom of an element does not represent the actual mass of its atom because the atomic mass listed on the periodic table is an average mass calculated based on the relative abundance of different isotopes of the element. Isotopes are atoms of the same element with differing numbers of neutrons, so the actual mass of an atom of a specific isotope may vary slightly from the average atomic mass.
What is the mass number of 15.9994?
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
Where in the atom is the mass of the atom concentrated?
It is the nucleus. Mass of electrons is too small
Where is he mass of an atom concentrated?
99.9% of the mass of an atom is located in the nucleus
Where is the most mass in an atom concentrated?
in the nucleus of the atom
Where is the mass of them atom concentrated?
in the nucleus
Most of the mass of an atom is concentrated in the?
in the nucleus of the atom
Where is all the mass of an atom concentrated in?
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
What is most of the atoms mass?
The mass of an atom is concentrated in the nucleus (protons+neutrons).
Is mass located in an atom's nucleus or in its protons?
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
Is the masss of an atom concentrated in the proton?
The mass of an atom is concentrated in the nucleus. Protons are a part of the nucleus, but not the entire thing. Neutrons are also in the nucleus and have nearly the same mass as protons.
Where is most of the atoms mass found?
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
An atom has no mass?
An atom does have mass. The mass of an atom is primarily concentrated in its nucleus, which is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
Mass of atom is contrated on what?
The mass of an atom is concentrated within its nucleus, which contains protons and neutrons. The electrons, which have negligible mass compared to protons and neutrons, orbit around the nucleus in specific energy levels.
