Carbon
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
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.
10 protons, 10 neutrons, 12 electrons
Atoms have 3 parts: Protons, Neutrons, and Electrons. In a neutral atom, the atomic #= number of protons, and everything else is equal to it. For example: Hafnium, Atomic#=72= 72 protons, 72 neutrons, 72 electrons= neutral atom.
The protons is 7, the neutrons is 8, and the electrons is 22.
Protons: 5 Neutrons: 7 Electrons: 5
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
protons= 74 neutrons= 110 electrons= 74
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
Atomic number is 6. The isotope is 6C11 Atomic number = number of protons = number of electrons (for a neutral atom)
