So 34 minus 16 gives 18, the number of neutrons in S-34. electrons ---> look at the atomic number. That's the number of positive charges in the atom, so 16 electrons makes the atom neutral. Since we have a 2- charge, we need to add in two more electrons.

Symbol: Na Atomic Number: 11 Atomic Mass: 22.98977 amu Melting Point: 97.72 °C (370.87 K, 207.9 °F) Boiling Point: 883 °C (1156 K, 1621 °F) Number of Protons/Electrons: 11 Number of Neutrons: 12 Classification: Alkali Metal Crystal Structure: Cubic Density @ 293 K: 0.971 g/cm 3 Color: silvery Atomic Structure

the same goes for electrons (assuming we're talking about stable elements, not ions) number of electrons is the atomic number as well. the number of neutrons should be the mass number (that big number with the ugly decimal) minus the atomic number.

Oftentimes part of your answer will be right in front of you in the periodic table! Once you know where to look, finding the number of protons, neutrons, and electrons will be a breeze. 2020-07-26 · Protons, neutrons and electrons The relative mass , relative charge and location in the atom for each subatomic particle is given in the table. Subatomic particle Since sodium (Na) has an atomic number of 11, this isotope contains 11 protons and 11 electrons. The number of neutrons in the isotope can again be calculated from its mass number, which is the numerical value written after the dash in both representations shown in Figure \(\PageIndex{2}\).

The mass number of Na (23) is the sum of its protons and neutrons. If there are 11 protons, then there are 23 - 11 = 12 neutrons. Therefore this Na atom has 12 neutrons. Neon has three stable isotopes: 20Ne (90.48%), 21Ne (0.27%) and 22Ne (9.25%).

Both protons and neutrons have a mass of 1, while electrons have almost no mass. Table 2.1 Charges and masses of the particles within atoms. Elementary

A = 23. Na. 23 is the average atomic mass. Z = 11. Now, you have only 10 electrons with 11 protons.
