Question
Chapter 2, Problem 1RQ
To determine
The formation of an ion from uncharged atom.
Expert Solution & Answer
Answer to Problem 1RQ
An uncharged atom consists of an equal number of protons and electrons. When an atom loses or gains the electrons, it becomes an ion.
Explanation of Solution
An atom consists of protons, neutrons, and electrons. Protons have a positive (+) charge and electrons have a negative (-) charge while neutrons are neutral in charge. The number of electrons and protons remain the same in an atom. The positive and negative charge of protons and electrons respectively balances the structure of the atom. As long as the number of protons and electrons remain same an atom is uncharged.
Whenever an atom gains or loses an electron, it becomes charged. The charged atom is called an ion. When an atom gains an electron the charge on the atom would be (-) and it is called anion. When an atom loses an electron the charge on the atom would be (+) and it is called cation.

- I need help with part A, B and Carrow_forwardDiscussion Question: Atmospheric Water & Weather A+ This chapter beautifully focuses on water from the small molecular scale to large-scale weather patterns. The surplus of heat at the equator and the deficit at the Poles drives our atmospheric instability. Instability is a good thing! Without the unstable conditions, there would not be any atmospheric motion. The overheating of the equator pumps atmospheric uplift. As the air rises into lower pressures, it expands and cools... adiabatic cooling! The air migrates north and south and becomes denser than the surrounding air and sinks. The sinking air enters higher pressures and creates the subtropical high pressures and adiabatic heating...whaaaa-la! We have Hadley Cells! Not to mention, the Rainforests and World's largest deserts too! We now can imagine the Hadley cells in three-dimensions.
