Which element has a higher melting point potassium in group 1A for calcium in group 1B?
Calcium, which is in Group 2 (not 1B, as there is no Group 1B), has a higher melting point than potassium, which is in Group 1. This is due to calcium being a metal with a higher atomic number and stronger metallic bonds compared to potassium, resulting in a higher melting point. Calcium's melting point is approximately 842°C, while potassium's is around 63.5°C.
What is potassium's number of valance electrons?
Potassium has one valence electron. It belongs to Group 1 of the periodic table, which means it has one electron in its outermost energy level.
What element is in group 2 and has fewer protons than potassium?
The element in group 2 with fewer protons than potassium is beryllium. Beryllium has 4 protons in its nucleus whereas potassium has 19 protons. Both elements are found in group 2 of the periodic table.
