the atomic number is the same as the number of protons
The number of neutrons in the nucleus is not the answer its wrong trust me Mass number = neutrons + protons. Atomic number = protons. Trust yourself to work out the difference.
Count the total number of electrons.
The atomic number of fluorine is 9.The atomic number of sodium is 11.
Atomic number= number of protons. Hydrogen atomic number=1
The atomic number is equal to number of protons in the atomic nucleus.
The number of protons is the atomic number of the element.
Atomic Mass minus atomic number
The number of neutrons in the nucleus is not the answer its wrong trust me Mass number = neutrons + protons. Atomic number = protons. Trust yourself to work out the difference.
The number of electrons in an atom is equal to the number of protons in the nucleus, which is the atomic number of the element. You can find the atomic number on the periodic table. For atoms that are neutral, the number of electrons is also equal to the number of protons.
At first, he did it by atomic mass, but that didn't quite work out right, so he changed it to atomic number.
this elemnt has an atomic number that is double the atomic number of silicon?
Count the total number of electrons.
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
Tungsten-187 has 113 neutrons. Work this out by subtracting the atomic number of 74 (which is the number of protons) from the mass number 187.
