How many protons electrons and neutrons are in an atom with an atomic number of seventy nine and an atomic mass of one hundred ninety seven?
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
In what way do these atoms corresponds and in what way do they differin terms of their mass numbers?
Atoms correspond in that they are all made up of protons, neutrons, and electrons. However, they differ in their mass numbers, which is the sum of protons and neutrons. Atoms of different elements have different mass numbers due to varying numbers of protons and neutrons.
Do isotopes of the same element differ in mass number?
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
Isotopes of an element differ in their?
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
What is the number of protons neutrons and electrons of carbon 12?
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
What Make up nearly all of an atoms mass?
The sum of all protons and neutrons - Apex Learning
What particles make up the mass of an atom?
The number of protons
