How many electrons do alkaline earth metals have?
Each has 2 valence electrons but the number of total electrons varies with each metal. Here they are for each metal. Beryllium: 4 Magnesium: 12 Calcium: 20 Strontium: 38 Barium: 56 Radium: 88.
Why is the melting point of calcium higher than the melting point of potassium?
Every element is different. The atomic number of potassium is 19 and calcium's is 20. Potassium's atomic mass is 39.098 and calcium is 40.08. these two elements are very different. Potassium being an Alkaline Metal while calcium is an Alkaline Earth Metal. You might be thinking. Oh my goodness those are like the same thing, but actually they are very different. Potassium just happens to less dense than calcium.
