What is the noble has gas with the lowest atomic mass?
Helium with an atomic mass of 4.00260
Gas atomic mass 16 8 nuetrons?
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
What is chlorine gases number of atomic mass?
Chlorine gas is Cl2. Cl's atomic mass is 35.45 and that x 2 is 70.9
What is the noble gas with lowest atomic mass?
Atomic mass increases from top to bottom and left to right on the periodic table. In each row, the noble gasses have the highest atomic mass. As you travel down that column, also called a group or family, the noble gasses increase in atomic mass. The naturally occurring noble gas with the highest atomic mass is Radon (Rn; atomic mass = 211.4 amu). In 2002, the unstable element Ununoctium was synthesized, and although it is a member of group 18, it was later determined to be a solid at room temperature, so it is not classified as a noble gas.
I have an atomic mass of of twenty and im a gas who am I?
You are likely referring to Neon (Ne), which has an atomic mass of approximately 20.18 atomic mass units. Neon is a noble gas, known for its lack of chemical reactivity and is commonly used in neon signs and lighting.
What is the atomic mass 20 gas?
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
What is the noble has gas with the lowest atomic mass?
Helium with an atomic mass of 4.00260
Gas atomic mass 16 8 nuetrons?
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
What element Nobel gas with atomic mass of 226?
Radon has atomic mass of 222. There is isotope of Radon with mass number 226. Radon is a Nobel gas.
What is the atomic mass for an argon gas?
Argon is a non meta element. Atomic mass of it is 40.
What is chlorine gases number of atomic mass?
Chlorine gas is Cl2. Cl's atomic mass is 35.45 and that x 2 is 70.9
What has atomic mass 20 and is a gas?
Neon.
What is the atomic mass 20 and is a gas?

What is hydrogen's atomic mass number?
Hydrogen is a gas. Mass number of it is 2.
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
