What is a gas and has as mass number of 19?
Fluorine is a gas with a mass number 19.
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
What is a noble gas with a mass of less than 15?
Helium
What is the noble has gas with the lowest atomic mass?
Helium with an atomic mass of 4.00260
What is the heviest noble gas?
Noble gases belong to group 0 and can be found on the extreme right column of the periodic table of elements. The heaviest noble gas would be radon, whose atomic mass is still uncertain. The element which appears below radon in the column, ununoctium, has not been confirmed as a noble gas.
Gas with mass number 19?
This gas is likely to be fluorine (F), which has a mass number of 19. Fluorine is a highly reactive, pale yellow gas that is part of the halogen group on the periodic table. It is commonly found in compounds rather than in its pure elemental form due to its high reactivity.
Is a noble gas with 48 neutrons and a mass of less than a 100?
The noble gas with 48 neutrons and a mass of less than 100 is Krypton. It has an atomic number of 36, which means it has 36 protons in its nucleus. The total mass of Krypton is slightly less than 100 atomic mass units.
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.
What element is a gas and has a mass number of 19?
The fluorine-19 isotope.
In certain mass of gas the number of atoms and the number of moleucules are equal How?
The gas has molecules that are single atoms, as do the noble gases.
Is krypton halogen noble gas or neither?
No, it is a noble gas
What is an element that is a Halogen Gas and with a mass less than 15?
No halogen gas has a mass of under 15 atomic mass units. The closest is fluorine, at 19.0 atomic mass units.
