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.
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?
The average atomic mass of the element would be the average of the atomic masses of the three isotopes. Since they occur in equal amounts, the average atomic mass would be the sum of the atomic masses of the three isotopes divided by 3. This average atomic mass is a weighted average, taking into account the relative abundance of each isotope.
What is the atomic mass of hg?
The atomic mass of mercury (Hg) is 200.59 grams per mole.
Which element Is an alkali metal with a mass greater than 200?
Francium is an alkali metal with a mass greater than 200 atomic mass units. It is the heaviest alkali metal and is highly radioactive, with a very short half-life.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
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.

What is the atomic mass of hg?
The atomic mass of mercury (Hg) is 200.59 grams per mole.
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.
Mass number of mercury?
The mass number of mercury is 200. This is obtained by adding the number of protons and neutrons in the nucleus of a mercury atom.
How was atomic mass first calculated?
The atomic mass was first calculated by chemist Joseph Louis Proust in the late 18th century by comparing the weights of different elements in chemical reactions. This pioneering work laid the foundation for the development of the modern atomic mass scale, which is now based on the carbon-12 isotope as the standard reference.
Mercury has an atomic number of 80 and a mass number of 200 How many neutrons are in one atom of mercury?
In one atom of mercury with a mass number of 200, there are 120 neutrons (mass number - atomic number = number of neutrons).
Which element Is an alkali metal with a mass greater than 200?
Francium is an alkali metal with a mass greater than 200 atomic mass units. It is the heaviest alkali metal and is highly radioactive, with a very short half-life.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
