The mass number of an atom is equal to?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
The mass number of an atom is equal to what?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
What number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
Is it true that the mass number of an atom can be less than the proton?
No, the mass number of an atom is always equal to or greater than the number of protons in its nucleus. The mass number is the sum of the protons and neutrons in an atom. If an atom had fewer protons than its mass number, it would be a different element altogether.
The mass number of an atom is equal to?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
What is the mass number of an atom equal to?
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
What does the atomic mass number an atom tell you about the atom?
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
What does the atomic mass number of an atom tell you about the atom?
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
Is the mass number of an atom equal to the atomic number?
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
The mass number of an atom is equal to what?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
What equal to the number of protons and neutrons in an atom?
mass number
What is the sum of protons and neutrons in an atom?
Mass number!:)
What equals the number of neutrons plus the number of protons in an atom?
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
