Q: The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to what number? Read this paragraph and choose the correct option from the provided answers: Electron configuration notation eliminates the boxes and arrows of orbital filling diagrams. Each occupied sublevel designation is written followed by a superscript that is the number of electrons in that sublevel. For example, the hydrogen configuration is 1 s 1 , while the helium configuration is 1 s 2 . Multiple occupied sublevels are written one after another. The electron configuration of lithium is 1 s 2 2 s 1 . The sum of the superscripts in an electron configuration is equal to the number of electrons in that atom, which is in turn equal to its atomic number. Choices: - metallic number - shell number - orbital number - atomic number A:
**Answer**
atomic number

Q: By pulling out grass by its roots and over-grazing, livestock contribute to what negative process? Read this paragraph and choose the correct option from the provided answers: As pictured below ( Figure below ), some grazing animals, especially sheep and goats, eat grass right down to the roots. They may even pull the grass entirely out of the ground. Grazing animals can kill the grass. They may thin it out so much that it offers little protection to the soil. If animals are kept in the same place too long, the soil may become completely bare. The bare soil is easily eroded by wind and water. Choices: - migration - evolution - immigration - erosion A:
**Answer**
erosion
