How do you find electrons on the periodic table?
Elements are placed in order on the periodic table based on their atomic number, how many protons they have. In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number.
How do you find the atomic number on the periodic table?
At the upper left is the atomic number, or number of protons. In the middle is the letter symbol for the element (e.g., H). Below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. At the very bottom is the name of the element (e.g., hydrogen).
How many protons neutrons and electrons are in neon 22?
The given isotope is neutral (uncharged). Therefore, it must contain 10 electrons to exactly balance its 10 protons.

What element has 10 protons 10 electrons and 12 neutrons?
Elements are defined by the number of protons they have. Neon, by definition, has 10 protons. If the atom is neutral, uncharged, it will have 10 electrons. There are three naturally occurring isotopes of neon, neon-20 with 10 neutrons, , neon-21 with 11 neutrons, and neon-22 with 12 neutrons.
What is the relative atomic mass of neon?
Neon Ne is one of the elements in the periodic table. It is considered a main group element and a noble gas. Neon has an atomic number of 10 and a mass number of 20.1797. Neon, Ne, is a noble gas and it is a gas that fills neon signs. It is element #10 in the periodical table. Its relative atomic mass is 20.1797.
