What element has 18 protons and 22 neutrons?
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.
What element has 8 protons 9 neutrons and 8 electrons?
The element with 8 protons, 9 neutrons, and 8 electrons is oxygen-17. Oxygen normally has 8 protons and 8 neutrons, but oxygen-17 is a rare isotope with an extra neutron. This gives it a total of 8 protons, 9 neutrons, and 8 electrons.
What is the element 54 protons 54 neutrons and 78 electrons?
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
What element has 18 protons?
The element that has 18 neutrons is ARGON... Wow, why didn't look in a periodic table? Is easier ask here??? Actually, 18 is argon's atomic number, and it also has 18 protons and electrons.. but it has 22 neutrons. The number of neutrons = mass number - number of protons. Soo, the answer is Chlorine, 17 protons, 17 electrons and 18 neutrons
The number of neutrons in an isotope of argon that has a mass number of 40 and an atomic number of 18?
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.
What element has 8 protons and 8 neutrons and is a gas?
Oxygen is the only element with 8 protons.
A gas element with 8 protons and 8 neutrons?
Oxygen
What element has 18 protons and 22 neutrons?
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.
How many protons electron and neutrons are in nitrogen?
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.
What does the element kryptonite composed of?
krpytonite is not an element! it is a made up element in Superman universe. A real element that has a similar name is the element Krypton. It is the 36th element . It is a noble gas. it is made up of 36 protons, and 36 electrons with an average of 48 neutrons. Just like any other element, it is made up of a different # of protons and neutrons with electrons floating somewhere around the nucleus. The # of protons in a nucleus is what makes the differences between elements.
What element has 8 protons 9 neutrons and 8 electrons?
The element with 8 protons, 9 neutrons, and 8 electrons is oxygen-17. Oxygen normally has 8 protons and 8 neutrons, but oxygen-17 is a rare isotope with an extra neutron. This gives it a total of 8 protons, 9 neutrons, and 8 electrons.
What gas has 8 neutrons and 8 patrons?
You mean protons, not patrons.The answer is Oxygen and more specially: neutrons + protons ---> 16O
What is the mass of gas?
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.
What is the element 54 protons 54 neutrons and 78 electrons?
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
A gas with 8 protons and 8 nuetrons?
An atom with 8 protons will have an atomic number of 8. Checking the periodic table, we see this element is oxygen. The isotope of oxygen with 8 neutrons is 16O.
What is atomic mass and number of gas molecule?
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.
What element has 18 protons?
The element that has 18 neutrons is ARGON... Wow, why didn't look in a periodic table? Is easier ask here??? Actually, 18 is argon's atomic number, and it also has 18 protons and electrons.. but it has 22 neutrons. The number of neutrons = mass number - number of protons.
