Question

26: (1 pt) represent the electron configuration of an ion of oxygen with its preferred charge using orbital notation
28: (1 pt) write the abbreviated electron configuration for a neutral atom of phosphorus with 1 excited electron
in 1976 in a hotel in philadelphia, pennsylvania, 2,000 veterans were attending the american legion convention. this was before copper pipes were used for air conditioners, and the pipes carried significantly more moisture and were excellent places for bacteria to grow. a never - before recognized bacteria, now named \legionella\ infected 186 attendees and killed 34 when they fell ill to the atypical pneumonia called \legionnaires disease.\ after this convention, copper pipes were introduced into plumbing systems across the nation. this is because copper (cu) interacts with microbes by rupturing their outer membranes, leading to loss of water and nutrients, and ultimately, death.
27: *based on what you know about elements, choose another element that would likely work well in plumbing and piping systems for similar reasons:
(a)silver, ag (b) zinc, zn (c) carbon, c (d) sodium, na
28: (1 point) explain your choice in question 27:
29: **(3 points) while walking home from school, you and your friends walk past the bodega and see the neon light \open\ sign to the right. explain to your friends how light is emitted from the atoms due to the movement of electrons. discuss both electron movement and energy transfer.

Explanation:

Silver (Ag) is in the same group (Group 11) as copper (Cu) in the periodic table. Elements in the same group often have similar chemical properties. Since copper can interact with microbes by rupturing their outer membranes, silver, with its similar chemical nature, is likely to have a similar antimicrobial property and thus work well in plumbing and piping systems for similar reasons.

Answer:

A. Silver, Ag
