The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
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.
What ratio can be used to predict the stability of an atom?
This is the protons/neutrons ratio in the atomic nucleus.
What number is used to determine how many electrons are in a neutral atom?
The number used to determine how many electrons are in a neutral atom is the atomic number, which is the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is equal to the number of protons, thus balancing out the positive charge of the protons with the negative charge of the electrons.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
What particule is used to determine the mass of an atom?
Protons, neutrons and electrons
What is an atom's mass number?
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
What characteristic of an atom is NOT used to determine the number of neutrons in an atom?
The characteristic of an atom that is not used to determine the number of neutrons is its atomic number. The atomic number indicates the number of protons in an atom, while the number of neutrons is derived from the difference between the atomic mass (which is the total number of protons and neutrons) and the atomic number. Therefore, only the atomic mass and the atomic number are needed to calculate the number of neutrons.
What does the Mass number in chemistry represent?
The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
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.
