What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
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 contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
If the atom has 14 protons and 12 neutrons what the atomic number?
The atomic number is the number of protons in an atom's nucleus, which in this case is 14. This is because the atomic number is determined by the number of protons in an atom, not the number of neutrons.
What particles are added together to determine atomic mass?
The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.
The atomic mass of an atom is determined by the combined masses of its what?
The atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. While electrons contribute very little to the atomic mass, the protons and neutrons, found in the nucleus, account for the majority of an atom's mass.
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
What makes an atoms mass number?
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
Can an atom be determined by knowing the number of neutrons?
No, only by the atomic number, also known as the number of protons.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
