How many protons are there in an atom the element lithium if it has an atomic number of 3?
Lithium has 3 protons. The atomic number and the number of protons will be the same.
Is hydrogens atomic number 1.008?
Hydrogen is a gas element. atomic number of it is 1.
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
What is a example of a non atomic number?
Mass number is the sum of neutrons and protons. It is equals to total of their weights. As an example hidrogen-2 (deuterium) has a mass number of 2.
Does an element's mass number tells the number of protons in its nucleus?
Close; Mass # is the number of protons + the number of neutrons.
When you subtract the atomic number from the atomic mass it will give you the number of what?
the protrons, neutrons and electrons in a atom
What equals atomic mass minus protons?
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
The combined number of protons and neutrons?
Number protons + number neutrons is called the mass number or the atomic mass.
The sum of the protons and neutrons in an atom equals the .?
atomic number
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
What is hydrgens atomic number?
Hydrogens atomic number is #1.
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
How do the mass number and the atomic number of an element different?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
Atomic mass equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
What does the atomic mass equals the number of?
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
How do the mass numbers and the atomic numbers of an element differ?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
84 protons, the same as the atomic number, and (210 - 84) or 126 neutrons. The numbers of protons and neutrons together equals the mass number.
