What is the relationship between melting point and atomic number for group seven elements?
As the atomic number increases so does the melting point, meaning the the molecules get stronger therefor you need a higher melting point to break the molecules.
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.
Which alkaline earth metal has the lowest atomic number?
This element is beryllium (Be).
Why do different materials have different melting points?
The melting point depends on the strengths of the forces between the particles. Different substances have different strengths and types of force.
Which is lightest alkaline earth metal?
The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.
Why is there a pattern between melting point and atomic radius?
A relation doesn't exist.

What are the relationships between the melting point and the atomic radius of an atom?
A relation doesn't exist.
What is the most reactive alkaline earth metal?
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
