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 is the sum of protons and neutrons in an atom?
Mass number!:)
How do you obtain the mass number of an atom?
The mass number of an atom is the total number of protons and neutrons in its nucleus. It can be obtained by adding together the number of protons and neutrons in the atom's nucleus. The mass number is typically written as a superscript to the left of an element's symbol.
What is the sum of a proton and nuetrons in the nucleus of an atom?
Its the mass number of an atom.The mass of an atom is concentrated in the nucleus. Both protons and neutrons which are collectively known as nucleons are found within the nucleus.Mass of electrons are not considered to be contributing towards the mass no. of an atom as their size is small and thus their mass is negligible.
What is the number of sulfur atoms that equal a mass of 32.07 amu?
One sulfur atom has an atomic mass of 32.07 amu. Therefore, to find the number of sulfur atoms that equal a mass of 32.07 amu, you would need just one sulfur atom.
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 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.
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.
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 the mass number of atom equal to?
proton
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 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 is the sum of protons and neutrons in an atom?
Mass number!:)
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
Why doest the atomic number equal the atomic mass?
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
