If an atom has an atomic mass of 101g and 57 neutrons, then:
Atomic Mass = (number of protions) + (number of neutrons) 101 = (X) + (57) or.... (101) - (57) = x 101-57=44 the element that has 44 as its atomic number would be Ruthenium
As we know mass of atom is primaril constituted by the neutrons and protons,while the mass of electron is neglegible.Taking mass of proton equal to mass of neutron and both having a unit mass.we can say that mass of an atom is equal to the number of protons and neutrons multiplied with the mass of i proton/neutron.
we are given mass of lithium =7
=>(no. of neutron + no. of protons)*(mass of 1 proton/neutron)=7
=>no. of neutrons + no. of protons *(1)=7
=>no. of neutrons=7-no. of protons
=>no. of neutrons=7-3 (atomic no=no. of protons)
=>no. of neutrons=4

To find the atomic number, subtract the number of neutrons from the Atomic Mass.
Atomic number = Atomic mass - Number of neutrons Atomic number = 101 - 57 Atomic number = 44
Therefore, the atomic number of the atom is 44.

Subtracting the Atomic number from the atomic mass?
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
What is atomic mass number minus protons?
The atomic mass number is the total number of protons and neutrons in an atom. Subtracting the number of protons will give you the number of neutrons in the atom.
If the atom has 14 protons and 12 neutrons what the atomic number?
The atomic number is the number of protons in an atom's nucleus, which in this case is 14. This is because the atomic number is determined by the number of protons in an atom, not the number of neutrons.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
Subtracting the Atomic number from the atomic mass?
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
How can you figure out the number of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
What is the atomic number of in atom?
The atomic number of an atom is equal to the number of protons in its nucleus. It determines the element's identity on the periodic table.
