How do u calculate atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.What is kryptonite atomic mass?

Copernicium is a chemical element with symbol Cn and atomic number 112. Classified as a transition metal, Copernicium is a expected to be a solid at room temperature.
Is copernicium a liquid?Copernicium is predicted to be a pale silver transition metal that is liquid or perhaps a gas at room temperature. Although only a few atoms of Copernicium have ever existed, it is predicted to be very dense. … The most stable isotope, copernicium-285, has an observed half-life of 29 seconds.

How many isotopes does copernicium have?
Isotopes: Copernicium has 5 isotopes whose half-lives are known with mass numbers from 277 to 285. None are stable. The most stable isotope is 285Cn, with a half-life of 34 seconds.
What does copernicium decay into?
Copernicium’s most stable isotope, copernicium-285, has a half-life of about 30 seconds. It decays into darmstadtium-281 through alpha decay. Since only a few atoms of copernicium have ever been produced, it currently has no uses outside of basic scientific research.

What is chlorine atom?
What is a chlorine atom? Chlorine is an atom that has 17 protons and usually either 18 or 20 neutrons in its nucleus and 17 electrons circling around its nucleus.
What is the mass number of Cl2?
17. Relative atomic mass. 35.45. State at 20°C.
Why is chlorine written Cl2?
Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2).
What is the atomic structure of chlorine?
Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons. As a member of the halogen family on the Periodic Table, chlorine is very reactive with metals and forms salts.
What is hydrogens AMU?
The atomic mass listed for hydrogen on the period table is 1.00794 amu. … Isotopes of an element have the same atomic number, but a different mass number. Hydrogen is the only element that has different names for its isotopes. Hydrogen with one neutron is also called deuterium, and the symbol is D.
