1. the valence electrons in nitrogen experience the 2 charge of the nucleus through the shield of core electrons. 2. the shielding experienced by any one of the valence electrons resulting from the core electrons is nearly nearly 6+. 3. for the 2s electrons, the shielding from the other 2s electron is nearly zero. 4. for the 2p electrons, the shielding from the other 2s electron is slightly greater than 5+. 5. therefore, the effective nuclear charge would be 6+. 6. the effective nuclear charge felt by the 2s electrons would be greater than the effective nuclear charge felt by the 2p electrons.

When a comet collides with earth, it adds material to our planet and causes great damage. therefore, a collision like this is a a. destructive force b. constructive force c. geologic process and event d. constructive and destructive force

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
