Being Cu-64 says it is copper. Copper has 29 protons in the nucleus. Since there are the same number of electrons as protons it must have 29 electrons. The number 64 indicates there are 64 particles in the nucleus. Sine 29 are protons, the rest must be neutrons so there must be 35 of these.

Find the Number of protons neutrons and electrons in xenon?
54 protons, an average of 77 neutrons, and 54 electrons.
What is the number of protons neutrons and electrons in the neutral atom bromine-80?
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
Determine the numbers of electrons protons neutrons 80 35 Br?
The element with atomic number 35 is bromine (Br). It has 35 protons and since it is neutral, it also has 35 electrons. To find the number of neutrons, subtract the atomic number (35) from the atomic mass (80). So, bromine-80 has 45 neutrons.
What element has 86 electrons 125 neutrons 82 protons?
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.
Find the Number of protons neutrons and electrons in xenon?
54 protons, an average of 77 neutrons, and 54 electrons.
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.
Do you have to add the protons and electrons in order to find the atomic mass of an atom?
no, you add the protons and neutrons
What is the number of protons neutrons and electrons in the neutral atom bromine-80?
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
How many protons neutrons and electrons does ion have?
The mass number for iodine is 131, which is the sum of the protons and neutrons. Iodine has 53 protons and 53 electrons, if neutral. To find how many neutrons iodine has subtract 53, the number of protons from the mass number of 131. This shows that iodine has 78 neutrons.
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
How can i find the Protons Electrons and neutrons for strontium with a mass of 83?
Well, honey, to find the protons, electrons, and neutrons for strontium with a mass of 83, you need to look at the periodic table. Strontium has an atomic number of 38, which means it has 38 protons and 38 electrons. To find the number of neutrons, you subtract the atomic number from the mass number, so for strontium-83, you have 45 neutrons. Voila!
What particles make up the mass of an atom?
The number of protons
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
Are protons neutrons and electrons atoms?
No they are not in the same way that arms and legs are not people.Protons, neutrons and electrons can come together in some specific numbers form atoms (or molecules). You can also have electrons by themselves. Normally you will not find isolated neutrons and protons. Alpha particles are 2 protons+2 neutrons which are found in radioactive decay.
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.
What atom had 26 protons 26 electrons and 30 neutrons?
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
