You look up antimony. You discover its symbol is SB. You look on your Periodic Table. You come to the symbol SB. You see that it is number 51. You know that is also the number of protons in the atom. You know that 122 is the atomic weight. You know that the Atomic Weight mainly comes from the weight of the neutrons and protons. You know that when you have the atomic weight you can subtract the atomic number from the atomic weight and get the number of neutrons.

How many neutrons are found in argon?
There are 18, 20 or 22 neutrons.
How many pounds is 122 kilogram?
A kg equals 2.204 pounds. You may do the math.
Is antimony a good conductor of heat and electricity?
Yes, antimony is a good conductor of both heat and electricity.
How many protons neutrons and electrons does antimony-123 have?
Protones = 51 Electrones = 49 Neutrones = 70 or 72

How many protons neutrons and electrons does iodine-122 have?
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
What is the proton neutrons and electrons for antimony?
51 protons, 51 electrons and 70 neutrons (in Antimony-171 isotope)
What is the number of subatomic particles for antimony?
Antimony has 51 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an antimony isotope = Mass number - 51
What is the atomic mass of Antimony?
Antimony is a meta element. Atomic mass of it is 122.
How many neutrons and protons are in 23290Th?
Thorium-232 has 90 protons and 122 neutrons.
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.
What are the number of protons for antimony?
Antimony (Sb) has the atomic number of 51. The atomic number is the same as the number of protons in the atom (an the same as the number of electrons in the neutral atom).
How many neutrons does seaborgium-212 have?
Atomic number = 106 So number of neutrons = 122 - 106 = 116
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.
Which element has 51 neutrons?
An element's number of protons is the same as its atomic number. Thus, an atom with 51 protons has the atomic number 51. By looking up this element on the periodic table, one finds that it is antimony.
