How many protons does sodium 12 have?
For sodium that means there are 11 protons and 11 electrons. Since we know that there are 11 protons there must be 12 neutrons for the mass number to equal 23 (23-11=12).
How do you find protons?
Finding the Number of Protons The number of protons in an atom is equal to the atomic number of the element. For example, let's use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element's symbol.
How many neutrons does sodium have?
12 neutrons Given the fact that there are 12 neutrons in sodium, the complete symbol for sodium is 2311Na.
How many electrons are in a sodium atom?
11 electrons Sodium has 11 electrons. The first two fill the innermost energy level. The second energy level is also full, holding eight electrons and one electron remaining in the outer energy level. It is the number of outer electrons that give an element its chemical properties.
How many atoms sodium have?
So… for the element of SODIUM, you already know that the atomic number tells you the number of electrons. That means there are 11 electrons in a sodium atom.
What has 16 protons and electrons?
If a sulfur atom has 16 protons, 16 electrons, and 16 neutrons, what is its atomic mass?

What is the element with 26 protons?
iron In February, we have selected iron, the most abundant element on Earth, with chemical symbol Fe (from the Latin word “ferrum”) and atomic number 26. A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus.
How do you find the number of protons?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
