In a complete sentence, describe the relationship between shielding and penetration. [textbook: Tro. 2^nd, p156, question 136]
Determine whether each statement regarding penetration and shielding is true or false. Explain. [textbook: Tro. 2^nd, p156, question 133]
1. An electron in a 3s orbital is more shielded than an electron in a 2s orbital.
2. An electron in a 3s orbital penetrates into the region occupied by core electrons more than electrons in a 3p orbital.
3. An electron in an orbital that penetrates closer to the nucleus will always experience more shielding than an electron in an orbital that does not penetrate as far.
4. An electron in an orbital that penetrates closer to the nucleus will tend to experience a higher effective nuclear charge than one that does not.
