Hydrogen has the atomic number of 1.
Aluminum (Al)
Li is atom number three, not only 'was' but it still is and ever will be.
He discovered that the weight of an electron is 1836 times smaller than that of a hydrogen atom (atomis mass of 1)
Atomic not Atomis!
To count the number of elements in a compound, you can identify the different elements present by looking at the chemical formula. Each element is represented by a unique symbol (e.g., H for hydrogen, O for oxygen). Count the number of unique elements present in the compound to determine the total number of elements.
the answer is 107.87
The atomic number tells you the number of protons the atom of an element has. The atomis is the smaller of the two numbers next to symbol of the element.
Atomis
No, the Atomic Mass is the full complete mass while the mass # is just the whole number. For example: carbon's atomis mass is 12.011 and the mass # is 12.
Is the number of protons in an atom determines its atomic number
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
The atomic number of hydrogen is 1, which means that a hydrogen atom has one proton in its nucleus.
