Which statement is true?

An orbital that does not penetrate into the region occupied by core electrons is less shielded from nuclear charge than an orbital that penetrates and will therefore have a higher energy. An orbital that does not penetrate into the region occupied by core electrons is more shielded from nuclear charge than an orbital that penetrates and will therefore have a higher energy. An orbital that does not penetrate into the region occupied by core electrons is less shielded from nuclear charge than an orbital that penetrates and will therefore have a lower energy. An orbital that does not penetrate into the region occupied by core electrons is more shielded from nuclear charge than an orbital that penetrates and will therefore have a lower energy.

Answer;

The true statement;

An orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy.

Explanation; The physical properties and chemical properties of elements is determined by the penetration and shielding principles. Penetration is the ability of an electron to get close to the nucleus, while shielding occurs as a result of the balance between attractive forces between the electron and the nucleus, and repulsive forces between electrons. The amount of charge felt by an electron is dependent on its distance from the nucleus. The closer an electron is to the nucleus, or the more it penetrates, then the stronger its attraction to the nucleus. Core electrons penetrate more and feel more of the nucleus than the other electrons.
