In addition to helping you reduce your calorie intake for weight loss, drinking hot lemon water may also help you meet your daily vitamin C and potassium needs. Juice from one lemon contains 11 calories, 18 milligrams of vitamin C and 49 milligrams of potassium.
Aluminum has 13 electrons in a neutral atom. The 1S2, 2S2 and 2P6 shells are full, and so is the 3S2. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two semi-valence electrons which can be loaned out.
Once one shell is full, the next electron that is added has to move to the next shell. So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.
