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.
The shell closest to the nucleus, the K shell, has a capacity for two electrons. The next shell, L, has a capacity for eight, and the third shell, M, holds up to 18.The atomic number for nitrogen is seven, which means it has seven protons and seven electrons in the atom. Two electrons are in the innermost K shell.
