What is the mass of a hydrogen nucleus?
The mass of a hydrogen nucleus is approximately 1 atomic mass unit.
Is the mass number the same as the atomic mass?
No, the mass number is not the same as the atomic mass. The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic mass is the average mass of all the isotopes of an element, taking into account their abundance.
Most of the mass of an atomic concentrated in the what?
Most of the mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. Electrons, which have a very small mass compared to protons and neutrons, orbit around the nucleus.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
How does Neutron emission from a nucleus affect an element?
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
What number tells the mass of the nucleus of an atom?
The atomic mass number is the mass of the nucleus in atomic mass units.
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
What is the mass of a hydrogen nucleus?
The mass of a hydrogen nucleus is approximately 1 atomic mass unit.
What is the atomic mass of atoms made of?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
What is the atomic mass of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
What is the difference between atomic number and atomic mass?
Atomic number refers to the number of protons in an atom's nucleus, which determines the element's identity. Atomic mass is the average mass of an atom of that element, taking into account the mass of protons, neutrons, and electrons. Atomic mass is measured in atomic mass units (amu).
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
What is the difference between the atomic number and atomic mass of an element?
Atomic number is the number of protons in the nucleus of the atom. But atomic mass is the mass of the nucleus and mass of the electrons around the nucleus. If suppose we say the mass number then it is the total number of protons and neutrons in the nucleus. Nucleon is the common name for both proton and neutron. Hence mass number is the total number of nucleons.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
What is atomic number or atomic mass?
ATOMIC MASS ;The total numbers of protons and neutrons present in the nucleus of an atom is called atomic mass and it is represented by A ATOMIC NUMBER;the number of protons in the nucleus of an atom are called atomic number or proton number and it is represented by Z
What is the atomic mass number?
The atomic mass number tells how many protons and neutrons are in a nucleus.
