We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What else can I help you with?
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
Can atoms of two different elements have the same atomic number and could they have the same mass number?
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
Can you find the atomic number of an element in the periodic table?
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
What information could you use to determine the atomic number of unknown element that has a mass number of 22?
To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
What is a unknown element that has a mass number of 22?
All elements that have an atomic mass of 22 are known. One example would be 22 sodium. Now, if you are talking about the atomic number of 22, that would be Titanium, which is also known.
If the atomic number of Element D is 20 then what is the atomic number of R?
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).
Has an atomic number of 7?
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.

What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
The element in group one with a higher atomic number than chlorine but lower atomic number than bromine is iodine. Its atomic number is 53, which is greater than chlorine's atomic number of 17 but less than bromine's atomic number of 35.
What element has the atomic number 238?
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
What does 33 mean in the periodic table?
could be either the atomic number or the mass number of the element, depending on what you are referring to.
Can you find the atomic number of an element in the periodic table?
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
How could physicists propose an element to put in a periodic table if sometimes like uranium have different atomic number and atomic mass?
The atomic number of the isotopes of an chemical element is the same; only the atomic mass of the isotopes is different. Also the isotopes of an element have the same chemical and physical properties (of course with some approximation).
What does the atomic number determmine?
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
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.
