How many neutrons dose aluminum-24 have?
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
What number represents the protons and nuetrons?
The mass number
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
How have scientists arranged varios atoms?
by number of protons and nuetrons
How do you calculate the amount of protons or neutrons in an element?
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons

What information must be known in order to calculate the mass number if an atom?
The mass number = the number of protons + the number of nuetrons. Each of these particles is considered to have a mass of 1 amu. (atomic mass unit) For example, Aluminum has 13 protons and 14 nuetrons, so it's mass number = 27.
What number represents the protons and nuetrons?
The mass number
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
What is the sum of the protons and nuetrons in an atomic number?
atomic number is the number of protons. the sum of protons and neutrons is known as mass number
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
What is the number of protons nuetrons and electrons?
12,13, and 26
How do you figure the number of nuetrons from the number of protons?
Mass number will help you. Mass number is the total of neutrons and protons.
What is the sum number of protons and nuetrons in the nucleas of a atom?
The Mass Number.
