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.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
