In order to find out how many protons a sodium atom has, you have to look at the periodic table. Sodium is Na on the periodic table and you look for the number on the top of the symbol and you can see that it has 11 protons. To find out how many neutrons, you have to subtract 11 from the mass number, which is 23. 23-11 = 12.
12 neutrons; 11 protons
Hello there!
The atomic number of an atom tells you an element's identity, and informs you of how many protons are present in the nucleus of the atom.
For example;
Potassium is an element with the symbol "K" on the periodic table that belongs in the Alkali Metal group, and has an atomic number of 19. This means that Potassium has 19 protons.
I hope this helps!
During the light reaction of photosynthesis Water molecules split apart.
1. Water molecules split apart
<u>Explanation:</u>
Photosynthesis is the method by which plants, some bacteria and some protistans, a eukaryotic organism utilise the energy from daylight to generate Water molecules split apart. This can be turned into pyruvate which issues adenosine triphosphate (ATP) by cellular breath. This light initiated chlorophyll will part the water particle. This procedure is called Photolysis. Water atom is part to discharge H+ particles and furthermore oxygen.
<h2>
Hello!</h2>
The answer is: The starting materials in a chemical reaction are called reactants... or can be called reagents too.
<h2>
Why?</h2>
The principal component in a chemical reaction are the reactants, after the reaction, we have the products and we could have reactants too (if they are not completed consumed).
For example, given the following reaction:
Reactants are: 2C2H6 and 7O2
Products are: 4CO2 and 6H2O
Have a nice day!
True because of the constant flow in and out of the estuaries and the ocean.
