The atomic number of an element is the number of protons contained within the nucleus of an atom of that particular element. Since each element has a different number of protons, elements can be placed into a table based on the number of these particles.
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.
The elements on the periodic table are arranged in ascending order by their atomic numbers. So just find your element on the Periodic Table and the number for that element, usually found in the top area of the box, is the atomic number. So, if you look at a periodic table, hydrogen (H) has an atomic number of 1, carbon (C) has an atomic number of 6, and nickel (Ni) has an atomic number of 28.
Look it up in "periodic table of elements" You can find the number of a particular element by looking at the Periodic Table; you can also do this by counting the number of protons in the nucleus.
The atomic number is the number of protons in the nucleus of an atom. Each element has its own unique atomic number, which you can find on the periodic table, as the periodic table is arranged in ascending order of atomic number.
Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
# protons = atomic number.
Look at the Periodic Table.
