Q1-write lewis diagram for a)ne, b)sb(z=51),c)rn, d)a neutral atom with 9 electrons

Explanation: Lewis structure is defined as the structure in which the element is shown with its valence electron represented as dots.

Valence electrons are the electrons present in the last shell.

Number of valence electrons = 8

Number of valence electron = 5

Number of valence electrons = 8

Number of valence electrons = 7

The lewis structures of all the elements are shown in the image attached.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
