the number of protons is the same as the number of electrons. it is also the atomic number
Protons = atomic number EX: Nitrogen has 7 protons
The atomic number IS the number of protons. if you are given the mass number, then subtract the number of protons from it.
Mass number will help you. Mass number is the total of neutrons and protons.
Number of neutrons + Number of protons
Yes, you can by the atomic number. The atomic number of zinc is 30, so zinc has 30 protons.
Look at it's atomic number. That shows the number of protons it contains
Number of protons= Atomic number Number of neutrons= Mass number-Atomic number Number of electrons=Number of protons (If there is no charge on the atom)
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.
The number of protons in an atom is equivalent to its atomic number, which is located on the periodic table. Atoms are neutral and thus have an equal number of protons and electrons, so the number of electrons is also the same as the atomic number.
To determine the charge of an atom, you count the number of protons in the nucleus. This number represents the positive charge of the atom, as protons are positively charged particles.
If you have both the mass number and atomic number you can figure it out, since the atomic number is the number of protons. Say the mass number is 13 and the atomic number is 8. 13-8 is 5, so you would have 5 neutrons.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
