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 number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
What is the unified atomic mass unit equal to?
Aunified atomic mass unit is equal to one-twelth the mass of a carbon-12 atom.
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
The mass number of an atom can be equal to the atomic number.?
Yes but only if there are no neutrons, such as in hydrogen (atomic number=1, relative Atomic Mass-1)
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
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.
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
What atomic mass is equal to the atom on the periodic table?
number of protons = atomic mass
What do atomic number and atomic mass mean?
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an 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+
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
The atomic mass of an atom is equal to?
the total mass of its protons, neutrons, and electrons.
What is the unified atomic mass unit equal to?
Aunified atomic mass unit is equal to one-twelth the mass of a carbon-12 atom.
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Is the atomic number of an atom equal to its number of protons and the atomic mass is equal to its number of neutron Protons?
yes
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.
