What is the sum of protons and neutrons in an atom?
Mass number!:)
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
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.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
What does the Mass number in chemistry represent?
the atomic mass incdicated the amount of protons and neutrons of the atom
What particles make up the mass of an atom?
The number of protons
What is the sum of protons and neutrons in an atom?
Mass number!:)
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
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.
Is the number of neutrons in an atom known as its mass number?
No, neutrons + protons = mass
How is an atomic number similar to mass number?
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
