That would be oxygen (16O).
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.
The atomic mass of a gas depends on the specific element that the gas is composed of. For example, the atomic mass of oxygen gas (O2) is approximately 32 g/mol, while the atomic mass of hydrogen gas (H2) is approximately 2 g/mol.
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.
The noble gas Neon (Ne) has an atomic number of 10
Helium with an atomic mass of 4.00260
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.
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.
The atomic mass of a gas depends on the specific element that the gas is composed of. For example, the atomic mass of oxygen gas (O2) is approximately 32 g/mol, while the atomic mass of hydrogen gas (H2) is approximately 2 g/mol.
Atomic mass is the mass according to the number of protons and neutrons in the nucleus of the atom. The actual mass is the average of the masses of the different isotopes of the same element (alternative forms of the same element with the same no of protons but different no of neutrons) accordong to the isotopes mass and abundance in the world.
Atomic Mass is the count of how many protons and neutrons an element contains. So, there is not really an answer to your question. It would depend upon what elements the gas is made up of.
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.
The element with 18 protons and 22 neutrons is argon. Argon has an atomic number of 18, which corresponds to the number of protons, and an atomic mass of 40 (approx.), which is the sum of protons and neutrons.
The noble gas Neon (Ne) has an atomic number of 10
The atomic number of argon (Z) is 18, which means it has 18 protons. The mass number (A) is 40, so subtracting the atomic number from the mass number gives you the number of neutrons. In this case, 40 - 18 = 22 neutrons.
An example of a nonmetal with 10 neutrons and a mass greater than 19 is fluorine (atomic number 9). Fluorine has 10 neutrons and an atomic mass of approximately 19. It is a highly reactive gas at room temperature and is commonly found in compounds rather than in its pure form.
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
