Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
Has chemical analysis of lunar rocks shown that chemical elements not listed in the periodic table exist on the moon?
No, elements are defined by the number of protons they have and the periodic table contains all the elements up to over 100 protons, much past this point they become very unstable and radioactively decay into lighter (less protons in the nucleus) atoms. Elements this heavy do not occur naturally so we would not find them on the moon.
What are the two small particles that make up matter?
Actually there are 3 small particles that are normally listed: neutrons and protons in the nucleus of an atom and electrons that exist in "orbitals" tied to the nucleus.
What does it mean oxygen has 8 protons?
In an Oxygen atom's nucleus, there are 8 protons. In a neutral atom, there are also 8 electrons. Oxygen also has an atomic (protonic) number of 8, meaning that it has 8 protons. On the periodic table, elements are listed according to increasing atomic numbers.
What number is the number protons an element has?
There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
Why modern periodicity consist the protons of any atom?
In the periodic table chemical elements ar listed after the number of protons in the atomic nucleus.

How does the periodic table list elements?
Elements are listed by the number of protons they contain starting with Hydrogen which has one proton.
How are elements listed on the periodic tabel?
They are organized by atomic number (the number of protons/electrons in the element).
Why can't atoms have 182 electrones?
The number of electrons in an atom equals the number of protons in its nucleus and is the element's atomic number. The periodic table does not contain any (stable) elements with 182 protons. It is possible for the isotopes of many elements to have an atomic mass (protons+neutrons) of 182, though. None of these isotopes are the most stable for the given element, and thus these are not listed on the periodic table. I think Tungsten has an atomic mass of 183?
How do you know protons are found in the nucleus?
The atomic number tells you how many protons are in the atomic nucleus. The atomic mass is the amount of protons plus the amount of neutrons in the atomic nucleus. So if you take the atomic number and subtract it from the atomic mass, it will give you the number of neutrons in the atomic nucleus.
What are the two small particles that make up matter?
Actually there are 3 small particles that are normally listed: neutrons and protons in the nucleus of an atom and electrons that exist in "orbitals" tied to the nucleus.
How do you determine the mass of an element?
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
How many protons are in sodiums most common isotope?
Eleven. This because sodium has an atomic number (also the number of protons) of 11 on the periodic table. All the elements listed on the table are the most common (or only) isotopes of those elements.
How many protons does an atom of the first element listed on the periodic table have?
Hydrogen, being the first element, has one proton and one neutron in its nucleus.
What element has the most protons calcium gold lithium or oxygen?
Gold has the most protons per atom, because it has a higher atomic number than any of the other elements listed.
