What else can I help you with?
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
What is the sum of protons and neutrons in an atom?
Mass number!:)
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
What element has 8 neutrons 8 protons?
The element that has 8 protons and 8 neutrons is oxygen.
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
What is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
Finding the number of neutrons in an element?
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
