Hot water and lemon may help you eat fewer calories. No doubt about it, lemons make a healthy addition to your diet. Theyâre low in calories and rich in antioxidants. But despite the claims, drinking hot water with lemon won't help you lose weight unless accompanied by a calorie-reducing diet.
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n 2) electrons.
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.
