Arrange the following atoms in order of decreasing atomic radius:Sr, Se, Ne, Zn

Arrange these elements in order of increasing atomic radius: F, S, Si, Ge, Ca, Rb.

Arrange these elements in order of decreasing atomic radius: Cs, Pb, Sb, Se, S.

Explain why atomic radius decreases as you move to the right across a period for main-group elements but not for transition elements.

Explain why vanadium (radius = 134 pm) and copper (radius = 128 pm) have nearly identical atomic radii, even though the atomic number of copper is about 25% higher than that of vanadium. Predict the relative densities of these two metals. Look up the densities in a reference book, periodic table, or on the Internet to check if your predictions are correct.

In which of the sets given are the atoms listed in order of increasing size (smallest to largest)?

Which of the following is true?
