How do you figure out protons electrons neutrons?
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
How many neutrons are found in an atom with atomic mass of 20?
Neon (Ne) has at. wt. of 20.183 and at. no. of 10.We know that the number of Protons is equal to At. No. and the number of Electrons equals the number of Protons.The number of Neutrons is the (At. Wt.) - (At. No.)Thus, we know that Ne has 10 Protons, 10 Electrons and 10 Neutrons.
An atom that is balanced or stable has the same number of negative charges as it does positive charges therefore you know that a balanced atom has an equal number of electron and?
protons and electrons .!.
What does atomic mass do?
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.

How do you calculate number of electrons required for the reaction?
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
What can be determined if you know the atomic number of an electrically neutral atom?
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
How do you know the number of electrons in a neutral atom?
The number of electrons will equal the number of protons in a neutral atom. And this will also equal the atomic number (the number of an element in the periodic table of Mendeleev).
What two pieces of information does the atomic number give?
The atomic number gives you the number of electrons and protons there are in an atom. ex: Carbon (C) has atomic number 6. So we know that it has 6 protons and 6 electrons

How many total electrons are present if the atom is electrically neutral in chlorine?
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
How do you determine the number of electrons in an atom if you don't know the number of protons or the atomic number in the atom?
The number of protons in an atomic nucleus is the sole determinate as regards its elemental identity - its atomic number. The number of electrons will exactly match this number in the neutral atom. But electrons can be loaned or borrowed. What is known? The number of neutrons? With nothing more than is stated, what can be determined? Nothing of a certainty. If the number of neutrons is known, then we could divide the table of elements into two parts: the group of elements that it "could be" and the group that it "couldn't be" by using a table of nuclides as a reference. Other than that, there is little that can be discovered....
How do you know how many electrons are in an atom?
Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom. In the case of an ion, adjust the number by the indicated charge; for example Na+1 will have 11 (the atomic number of Na) - 1 (since electrons have a negative charge, you subtract the charge) = 10 electrons.
What is the number of protons in atoms of a given element?
The number of protons is equal to the element's atomic number on the periodic table. Hydrogen, atomic number one, has one proton. Carbon, atomic number six, has six protons. Alternatively, if you know the number of electrons on a neutral atom, the number of protons will be the same.
