Question

4 multiple choice 1 point which of the following best explains why nitrogen and oxygen can form ions during a lightning storm? high - energy collisions break apart atoms, forming isotopes. the energy from lightning excites atoms enough to transfer or remove electrons. the gravitational pull of the cloud separates the charges in molecules. lightning causes protons to leave the nucleus. 5 multiple choice 1 point which atom would most likely form a negative ion in a lightning strike cloud? sodium (na) magnesium (mg) oxygen (o) aluminum (al)

Explanation:

For question 4, ions are formed when electrons are transferred or removed. Lightning provides high - energy that can excite atoms to do so. High - energy collisions forming isotopes is incorrect as isotopes are related to neutron number changes, not ion formation. Gravitational pull is not relevant for this ion - formation process and protons do not leave the nucleus easily.
For question 5, non - metals tend to gain electrons to form negative ions. Among the options, oxygen is a non - metal. Sodium, magnesium, and aluminum are metals which tend to lose electrons to form positive ions.

Answer:

1. The energy from lightning excites atoms enough to transfer or remove electrons.
2. Oxygen (O)
