What is the atomic mass of hg?
Mercury is a metal element. Atomic mass of it is 200.
Is there an atom with an atomic mass of 200?
Yes. There's even a stable atom with an atomic mass of 200 (well, not QUITE 200): Mercury has a stable isotope with a mass of 199.9683. Several other elements (platinum, gold, lead, etc.) have isotopes with atomic mass near 200, but they're all radioactive.
How was atomic mass first calculated?
The atomic mass is determined by accurate mass spectrometry. If you think to atomic weight, 200 years ago, this parameter was related to hydrogen with a given atomic weight of 1.
Suppose a newly discovered element has three isotopes that occur in nature Assume that these isotopes occurr in equal amounts in nature What will be the average atomic mass of this element?
You would add 200+203+209 and get 612. Then divide 612 by three. (612/3) to get that the average atomic mass is 204.
Which element Is an alkali metal with a mass greater than 200?
Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
What if theres an element called centium and it has 3 isotopes centium-200 centium-203 and centium-209 what is the average atomic mass?
I'm not sure, but i think it's 32, but don't count on it.
Which element has an atomic mass of 200?
Mercury has an atomic mass of 200.
What is the atomic mass of mercuny?
Mercury is a metal element. Atomic mass of it is 200.
What is the atomic mass of hg?
Mercury is a metal element. Atomic mass of it is 200.
Mass number of mercury?
Mercury is a non metal element. Atomic mass of it is 200.59.
Is there an atom with an atomic mass of 200?
Yes. There's even a stable atom with an atomic mass of 200 (well, not QUITE 200): Mercury has a stable isotope with a mass of 199.9683. Several other elements (platinum, gold, lead, etc.) have isotopes with atomic mass near 200, but they're all radioactive.
What is the average atomic mass of an atom?
The average atomic weight (not mass for elements) of a chemical element is calculated taking into account the isotopic composition of this element and the atomic masses (not weight for isotopes) of these isotopes.
How was atomic mass first calculated?
The atomic mass is determined by accurate mass spectrometry. If you think to atomic weight, 200 years ago, this parameter was related to hydrogen with a given atomic weight of 1.

Francium is the heaviest of the alkali metals, with an atomic mass of 223 grams.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
What will be the no of neutrons protons of hg having mass no 200 atomic no 80?
The number of protons = the atomic number. The number of neutrons = the mass number - the atomic number Protons = 80 Neutrons = 120 Also, for extra information, not that you need it, the element would be mercury.
