A nonpolar molecule is entirely symmetric. For a molecule to be nonpolar, it must have at least a linear, trigonal planar, or a tetrahedra shape. However, that’s not totally enough. For the molecule to be completely symmetric, aside from having a symmetric shape, all of the atoms that are connected to the central atom must be alike. Therefore, symmetry has two components, they are the geometric arrangement of the outer atoms and whether or not they are all the same.
Fundamentally, non-uniform or it is the uniform, distribution of electrons that ascertains if a molecule is polar or nonpolar, but this distribution is established by the dispersal and distinctiveness of the atoms in a molecule.
Answer:
A) The energy of a given orbital increases as the nuclear charge Z increases.
Explanation:
The energy of an orbital is as higher as the attraction force between protons and electrons is lower. So, as far as from nuclei, the orbital is more energetic. When Z increases, that means that the number of protons increases, so the attraction force increases, then the energy of a given orbital decrease.
Letter "b" is correct because of the Linus Pauling diagram in which the levels and sublevels are displaced to know its energy. The sublevel 3d is more energetic than the sublevel 4s, so it's necessary both quantum numbers.
Letter "c" is correct because the electrons at the same orbital have a greater repulsive force, so they can't shield electrons at the same orbital. But the inner electrons are attracted to the nuclei, so the repulsive force, plus the distance, will be less effective.
Letter "d" is correct because the penetration effect means the ability of an orbital to attract an electron. So, when the division in sublevels can explain that energy from the orbitals.
Letter "e" is correct because in the hydrogen atom there is only one orbital with one quantum number n and one quantum number l, which are n = 1, l = s, so the energy depends only on the quantum number n.
Well group 7 are all known elements of transition metals Rf is period 4 :) pls give me brainliest
