the atomic notation is 7 x 4940 equals folowing
The number of protons in an atom.
Extract from the mass number (in the hyphen notation) the atomic number.
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
The isotopic notation for carbon-14 is ^14_6C. This notation indicates the atomic number (6, which represents carbon) as a subscript and the mass number (14) as a superscript.
Subtract the atomic number from the atomic mass after rounding each.
The standard atomic notation for an atom of argon with 20 neutrons and 18 protons is 38Ar.
The standard atomic notation for the sodium-23 atom is: Atomic number (number of protons) = 11 Mass number (sum of protons and neutrons) = 23 Symbol = Na Putting it all together: ^23Na
183W (Tungsten)74109
It would be 9 on top, 4 on bottom and then Be.
2411Na, which is sometimes written more simply as 24Na, since all Na atoms have 11 protons.
An atom of sodium with an atomic number of 11 and mass number of 24 is 2411Na.
Mrs Hanger
The number of protons in an atom.
Extract from the mass number (in the hyphen notation) the atomic number.
A chemical formula
Atomic number of a atom is same as the number of protons of the same atom
The atomic number is the number of protons and therefore, assuming the atom is neutral, the number of electrons. You would need to additionally know the atomic mass to figure out the number of neutrons.
