Neutrons need not be considered here. There are 3 more electrons, the negatively charged subatomic particle, than there are protons, which are positively charged. So;
3(-) is the charge on the atom.
The number of protons and electrons can be found by looking at the atomic number if it isnt an isotope. The number of neurons can be found by subtracting the Atomic Mass by the number of protons
The 33 protons make it arsenic. The 42 neutrons make it As-75. This is the only naturally occurring and stable isotope of this chemical element.
This is the anion of the isotope arsenic-75: 75As3-; it is impossible to write correct in WikiAnswers.
Oxygen-16: 8 protons, electrons and neutrons
Oxygen-17: 8 protons and electrons, 9 neutrons
Oxygen-18: 8 protons and electrons, 10 neutrons
Arsenic most likely!
30 electrons

Neutral.
16 protons, 17 neutrons, 16 electrons.
The atomic number of an atom is the number of protons, so this atom has an atomic number of 27, which makes it cobalt, with the symbol Co. The isotope of cobalt that contains 27 protons and 27 neutrons has a mass number of 54, which is the sum of the protons and neutrons in the nucleus of the atom.
S with 17 neutrons and 16 protons has a mass number of 33 amu
Arsenic is a non metal element. There are 33 electrons in a single atom.
Krypton is a noble gas with atomic number 36. However, the number of neutrons in Krypton can vary from 33 to 64, depending on the isotope. So, in a neutral Krypton atom, there are 36 protons, 36 electrons and 33-64 neutrons.
Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.
That atom is Arsenic. It would have 33 electrons.
16 protons, 17 neutrons, 16 electrons.
Number of nucleons = number of protons + neutrons = 16 + 17 = 33 The mass number is thus 33 and the atom is denoted sulfur-33 or 33S.
Krypton has an atomic number of 36.
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
The atomic number of an atom is the number of protons, so this atom has an atomic number of 27, which makes it cobalt, with the symbol Co. The isotope of cobalt that contains 27 protons and 27 neutrons has a mass number of 54, which is the sum of the protons and neutrons in the nucleus of the atom.
The number of protons in an atom will always be the same as the atomic number, by which the periodic table is organized. So figuring out how many protons an atom has just becomes an exercise at reading the table. In this case, aluminum has an atomic number of 13. If the particle is specifically an atom, then it will be neutral and the number of electrons will balance the number of protons exactly. The number of neutrons will differ depending on the isotope - atoms of the same element with different numbers of neutrons. Although, almost 100% of aluminum is 27Al with 14 neutrons.
There are about 33 isotopes of arsenic. Only one of them is stable, and that's 75 As 33. All the other isotopes are synthetic.
S with 17 neutrons and 16 protons has a mass number of 33 amu
Mass Number= 33+27=60
Arsenic is a non metal element. There are 33 electrons in a single atom.
