Mercury (Hg) has an average Atomic Mass of 200.59. This is an average based on the percentages of the naturally occurring isotopes of Mercury. There is an isotope of Mercury that has 201 particles in the nucleus. Since Mercury's atomic number is 80, Mercury-201 has 80 protons and 121 neutrons in its nucleus.

∙ 11y agoMercury, because 201-121=80 protons. this also means the atomic number of the element is 80 therefore being mercury

What is the atomic mass of Antimony?
Antimony is a meta element. Atomic mass of it is 122.
How many protons are in Lead 204?
This is actually a very, very easy question to answer. Now, all atoms of the same element have the same number of protons. Otherwise, they wouldn't be the same element. For instance, if lead had one more proton, it would be bismuth, a non-toxic shiny metalloid. If it had one less, it would be thallium: a deadly poison which was only recently found. Lead has 82 protons. When the number is given by an element name (e.g. lead-204), it is also showing the atom's nucleus' mass number. Natural lead contains lead-204, lead-206, lead-207, and lead-208. Each of these contains the same number of protons, but different numbers of neutrons, hence the mass difference. To find the number of neutrons, N, we subtract the number of protons, Z, from the mass number, A. So, 204 - 82 = 122. Lead-204 contains 122 neutrons.
How many protons neutrons and electrons does iodine-122 have?
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
What is element mercury mass number?
Perhaps you should google "Mercury's atomic mass" I'm sure there are thousands of sites out there that could help you out. Or, if you're feeling adventurous, maybe you could look at a periodic table.
How many neutrons are in 202Hg?
122
How many neutrons are in antimony 122?
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 does seaborgium-212 have?
Atomic number = 106 So number of neutrons = 122 - 106 = 116

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.
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
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 are present in Hg?
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
How many protons neutrons and electrons does iodine-122 have?
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
How many neutrons in bismuth-205?
Bi-211 (and all other Bi isotopes) has atom number 83, hence there are 83 protons.
