How many proton and electron in antimony 121?
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.
What is the protons neutrons and electrons for mercury?
Atomic weight of mercury is 201 80 protons 80 electrons 121 neutrons Mercury has 7 stable isotopes, with 116, 118, 119, 120, 121, 122 and 124 neutrons. The 116 neturon isotope is pretty rare on Earth (0.15%).
Protons neutrons and electrons for mercury?

How many neutrons does antimony contain?
Antimony (symbol Sb) has three isotopes: 121Sb, 123Sb, and 125Sb. The 121 isotope has 70 neutrons, and the 123 isotope has 72 neutrons. The 125 isotope isn't stable and will decay, but it has 74 neutrons.
How many protons and electrons does mercury have?
Mercury (Hg) can ONLY have 80 protons, or else it cannot be mercury. The difference between its mass number (201) and 80 is 121, which is the number of neutrons. These can vary and are called isotopes. The number of protons can always only be 80 for mercury, tho.
What element has 21 neutrons?

If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons does the atom have?
80
What is the number of neutrons and electrons of mercury?
The atomic number of Mercury(Hg) is 80; since atomic number of an atom= No. of protons.Thus No. of protons in Mercury is 80. Also No. of protons = No. of electrons (In an neutral Atom; which is not an ion).Therefore No. of electrons is also 80. Next, Mass number(Atomic Mass) of Mercury is 160. Mass Number(Atomic Mass)= No. of Protons + No. of Neutrons. Hence calculating that we get No. of Neutrons also to be 80. FYI; Electrons have negligible mass so they are not included in calculating Mass of an atom, which only requires the nucleus which contains only protons and neutrons
If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons would Bohr say the atom has A. 41 B. 80 C. 121 D. 201?
