Sodium is a metal element. Atomic Mass of it is 23.
Sodium is a metal element. Mass number of it is 23.
Sodium is a meta element. Atomic mass of it is 23.
Use avagadro's number - states the number of atoms in 1 mole of a substance: 6.022 x 10^23
To find the mass of 6.02 x 10^23 atoms of an element, you would multiply the atomic mass of the element (x) by Avogadro's number (6.02 x 10^23 molecules/mol) to get the mass in grams. The result would be x grams.
Elements differ from one another according to the number of protons in the atoms' nuclei. Essentially, the number of protons indicate the element (not its reactivity).11 is the atomic number of SodiumAtomic number (in this case, 11,) is the number of protons in the element.The 23 is telling you the atomic mass of the element (usually listed underneath the element symbol on the periodic table). The atomic mass of Sodium on the table is usually around 22.989.... so rounded to 23 for you in this question.The atomic mass is the mass of protons plus neutrons(each about 1 atomic mass units).Electron are so relatively light they do not significantly contribute to the mass of an element.

Sodium is a metal element. Atomic mass number of it is 23.
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).

Sodium is a metal element. Atomic mass of it is 23.
Vanadium, Symbol V, is the element with atomic number 23.You can find the atomic number of an element from a periodic table as the one you'll find if you follow the link below. The number to the top of an element's symbol is the atomic number (that is , the number of protons in the nucleus.)http://www.electrical-res.com/EX/10-17-19/periodic_table_of_elements.jpg
Sodium is a metal element. Mass number of it is 23.
Sodium, symbol is Na
The element is sodium with a mass number of 23. Sodium has 11 protons and thus an atomic number of 11. The mass number is calculated by adding the number of protons and neutrons, which gives 23 in this case.
