Yb.
Ytterbium, from the lanthanide series.
We know that sodium is atomic number 11, and it has 11 protons, 11 electrons (in a neutral atom), and will have 12 neutrons in its sodium-23 isotope. Sulfur is atomic number 16, and will have 16 protons, 16 electrons (in a neutral atom), and will have 16 neutrons in it sulfur-32 isotope. Oxygen has atomic number 8, and has 8 protons, 8 electrons (in a neutral atom) and will have 8 neutrons in its oxygen 16 isotope. If we take 2 sodium atoms, a sulfur atom and 4 oxygen atoms, we'll have a total of 70 protons, 72 neutrons and 70 electrons in sum.
Titanium has an atomic number of 22, meaning it has 22 protons in its nucleus. In a neutral atom, it also has 22 electrons. The most common isotope of titanium, titanium-48, has 26 neutrons. Therefore, a typical titanium atom contains a total of 70 subatomic particles (22 protons + 22 electrons + 26 neutrons).
Atoms gain or lose electrons so they have the same amount of electrons as the nearest noble gas. If you came across this question in the Science 10 textbook, page 39, the answer is found on page 35, bottom paragraph, 4 sentences in. I do have to say the question isn't well written.
In the isotope (^{70}{30}\text{Zn}), the atomic number is 30, which means it has 30 protons and 30 electrons (as it is neutral). The mass number is 70, so the number of neutrons can be calculated by subtracting the number of protons from the mass number: (70 - 30 = 40). Therefore, (^{70}{30}\text{Zn}) has 30 protons, 40 neutrons, and 30 electrons.
The atomic number of an atom tells you how many protons are present in the nucleus. So there are 50 in the element. By the way, an element with 50 protons and 70 neutrons (120-50) is a stable form of Tin.
the atomic number of Yb is 70. So there are 70 protons and electrons

Oxygen has atomic number 8, and has 8 protons, 8 electrons (in a neutral atom) and will have 8 neutrons in its oxygen 16 isotope. If we take 2 sodium atoms, a sulfur atom and 4 oxygen atoms, we'll have a total of 70 protons, 72 neutrons and 70 electrons in sum.
32 electrons, an atom has the same amount of electrons as protons.
it is 169
Yb is a non metal element. There are 70 electrons in a single atom.
The mass of a neutral atom is the sum of the protons and neutrons. If an atom has 31 electrons, it must also have 31 protons to maintain neutrality. Adding the 31 protons and 38 neutrons gives a total mass of 69 atomic mass units (amu).
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 70 protons and 99 neutrons, so the mass number would be 70 + 99 = 169.

Remember: p+ + n = m => n = m - p+ AND e- = p+p = number of protons = atomic numbern = number of neutronsm = mass number = (by definition) number of protons + number of neutronse- = electrons, valuable only for (neutral) atomic elementsAnswer:n = m - p+ = 120-50 = 70 neutrons in 50Sn(70), the most common isotope of tin (33%)e- = p+ = 50 = 50 protons and 50 electrons in 50Sn(70), tin, metal element in group 14.
Antimony, Sb, has the atomic number 51. The atomic number is the number of protons in the nuclei of all antimony atoms, so Sb atoms have 51 protons. In a neutral atom, the number of protons equals the number of electrons. So Sb atoms also have 51 electrons. Antimony-121 is an isotope of antimony with a mass number of 121. From the mass number, we can subtract the number of protons and get the number of neutrons in the atoms of the 121Sb isotope, which is 121-51 = 70 neutrons.
Three. For more information on Yttrium, go to http://en.wikipedia.org/wiki/Yttrium.
The isotope of tin-120 has 70 neutrons in its nucleus. Tin, element 50 on the periodic table, typically has 50 protons. By subtracting the atomic number (protons) from the atomic mass (protons + neutrons), we can determine the number of neutrons.
