- Gold-201 is a beta/gamma emitter with a 26 minute halflife.
- Mercury-201 is stable and makes up 13.22% of natural Mercury.
- Thallium-201 is a gamma emitter decaying by K capture with a 72 hour halflife.
- Lead-201 is a gamma emitter decaying by K capture with a 8.4 hour halflife (or less depending on isomer).
Other elements can be produced with an AMU number of 201, but there halflives are really too short to be of practical interest.

What is the atomic mass of the element Ne?
Neon is a non meta element. Atomic mass of it is 20.
What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
What element that has an atomic mass of 14.007?
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Which element has an atomic mass of 200?
Mercury has an atomic mass of 200.
What element has an atomic mass of 50.942?
Vanadium is the element that has an atomic weight of 50.942.
What is the atomic mass of the element mercury?
The atomic mass of mercury is approximately 200.59 grams per mole.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
Atomic mass is 201 what is the atomic number?
The atomic number is the number of protons in an atom's nucleus. Given an atomic mass of 201, this information alone does not provide the atomic number as different elements can have the same atomic mass due to isotopes. More specific information about the element is needed to determine the atomic number.
What is the atomic mass number of the most common isotope for mercury?
The most common isotope of mercury is mercury-202, which has an atomic mass number of 202.
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
What is the atomic mass for magnesiam?
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
What does the atomic mass describe?
The atomic mass describes the average mass of an atom of an element, taking into account the different isotopes and their relative abundance in nature. It is usually expressed in atomic mass units (amu) or grams per mole.
Which element has an atomic mass of 16.00?
the element that has an atomic mass of 16.00 is sulfer.
What is the atomic mass of the element iron?
Iron is a meta element. Atomic mass of it is 56.
