Question

Arrange Silicon Germanium and Flerovium in inceasing order in terms of atomic size

Answer 1

Answer:

silicon, germanium, flerovium

Answer 2

Explanation:

The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases. Moving down a group in the periodic table, the number of filled electron shells increases. In a group, the valence electrons keep the same effective nuclear charge, but now the orbitals are farther from the nucleus. Therefore, the nucleus has less of a pull on the outer electrons and the atomic radii are larger. Therefore the correct increasing order is given

N<Be<S<Al<Mg
