How do you use atomic number and average atomic mass to calculate the number of each of the three subatomic particles?
The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
What is the mass of 2 moll of carbon?
It is approximately 24.02 grams. Each mole of carbon weights 12.01 grams (one mole= enough particles to make a substance's weight in grams equal to it's atomic weight in amu; same amount of particles for every substance).
What two particles are equal to the atomic number?
No. of electrons and no. of protons are equal to atomic no. Since, protons are positively charged and electrons are negatively charged They cancel each other's charge and hence, the atom is neutral as a whole.
What subatomic particles contribute to the atomic mass of an atom?
Though today we know that an atom is made up of 3 types of sub-atomic particles (electrons,protons and neutrons) but it is found that each electron has a mass very less in comparison to the mass of other particles.So, its mass is taken to be negligible and is not counted to be contributing to mass of entire atom.On other hand, protons and neutrons have noticeable masses and are almost equal to each other in masses.These both are found in nucleus of atom and are considered to be contributing to the mass of the atom.
Is the atomic number of an atom equal to the number of neutrons?
Only be coincidence; the atomic number is defined as the number of protons in a nucleus of each atom of the element.
Two particles each have a mass approximately equal to one mass?
It is possible.

How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
Which two subatomic particles are present in equal numbers in an atom?
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
What is the charge of the particles in the nucleus of an atom?
Protons are each +1 and neutrons are neutral, giving the nucleus an overall positive charge equal to the number of protons in it, which is also the atomic number for that element.
Why atom is electrially neutral?
All atoms contain three sub-atomic particles: protons which are positively charged, electrons which are negatively charged, and neutrons which have no charge. The number of protons in an atom is equal to the number of electrons. Therefore the charges of the sub-atomic particles cancel each other out and the overal charge of the atom is neutral.
Which property causes atomic particles to attract or repel each other?
electric charge
For the element with atomic number 36 how many of each of the three subatomic particles are contained in this element the atomic mass of this element is 83.798amu?
The atomic number is 5becuse it is in the nuclise
What are the three atomic particles and the charge of each particle?
Neutron - no charge, Proton +1, Electron -1
What number is each element defined by?
Its atomic number, equal to the number of protons in each atom of the element.
