What is the atomic mass number of the most common isotope for mercury?
Mercury is a metal element. Mass number of it is 201.
What does the atomic mass describe?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
What is the atomic mass of the element mercury?
201
What element has a mass number of 122 and 72 neutrons?
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.

How many electrons are present in an atom of mercury whose mass atomic number is 80 and whose mass number is 201?
no of electrons in any atom is equal to the atomic number of that element so no of electron is 80
How can the number of neutrons in an atom be determined?
1. Locate the element on the periodic table.2. Find the element’s atomic number (which is the same as the number of protons)3. Find the element’s atomic weight.4. Round off the atomic weight to the nearest whole number to find the atomic mass.5. Subtract the atomic number from the atomic mass (The numbers after the decimal point represent the usually very small mass of the electrons in the atom.)

How can you tell how many neutrons are in an element?
The number of neutrons in an element is determined by subtracting the atomic number from the atomic mass number rounded to the nearest whole number. On the other hand, very few atoms are abnormal and have a different amount of neutrons than other atoms of the same element. These are called isotopes and are indicated by a number following the element symbol (eg. C-14). This is a radioactive isotope of carbon that has six protons based on the atomic number and two more neutrons than normal--8. (8+6=14). Finally, the reason that the atomic mass units end in decimals is that this is just an average weight. The isotopes can either bring this number up or down. atomic number [ 6 ] symbol [ C ] mass (atomic mass units (amu)) [ 12.01 ]
What is the mass of mercury Hg?
The atomic mass is 201 (rounded to whole numbers). Is that what you needed?
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 atomic numbers of first 20 elements?
Atomic Mass of the mainly occurring isotopes) of the first 20 elements (rounded figures)Ordering on atomic number 1 - 201 H4 He7 Li9 Be11 B12 C14 N16 O19 F20 Ne23 Na24 Mg27 Al28 Si31 P32 S35.5 Cl36 Ar39 K40 Ca*) But actually there are about 85 'different mass' isotopes from these 20 elements.K on its own already has 4 different isotopes with mass numbers, ranging from 39 to 42Ca on its own already has 9 different isotopes with mass numbers, ranging from 40 to 48
