Chapter 2: Q4TYU (page 28)

Which statement is true of all atoms that are anions?

(A) The atoms have more electrons than protons.

(B) The atom has more protons than electrons.

(C) The atom has fewer protons than does a neutral atom of thesame element.

(D) The atom has more neutrons than protons.

Short Answer

Expert verified

(A) The statement 鈥渢he atoms have more electrons than protons鈥� is false.

(B) The statement 鈥渢he atom has more protons than electrons.鈥� is true.

(C) The statement 鈥渢he atom has fewer protons than does a neutral atom of the same element鈥� is false.

(D) The statement 鈥淭he atom has more neutrons than protons鈥� is false.

Step by step solution

01

Explanation of option ‘(A)’

The molecule or atom that possesses the charge is referred to as ions. Atoms consist of protons, neutrons, and electrons. There are two types of the ions such ascation and anions.The element that has more electrons compared to protons is referred to as anion.

The positive charge is due to protons, and the negative charge is due to the presence of electrons鈥攊ncreased electron count results in the formation of the anion.

Thus, electrons are the determining factors in the formation of the anion.

Therefore, the given statement is true.

02

Explanation of option ‘(B)’

The positive charge is due to the presence of protons in theatoms. So, the increase in the number of protons results in the formation of the cations.

Thus, the protons are not responsible for the charge in theanion.

Therefore, the given statement is false.

03

Explanation of option ‘(C)’

The neutral atoms are the neutrons that are equally present inthe nucleus compared to the protons. The number of protons is more compared tothe neutrons and results in the formation of cations.

Thus, the cations formed due to the increase of the protons are opposite to the anions.

Therefore, the given statement is false.

04

Explanation of option ‘(D)’

Neutrons of the atoms do not contain any charge and are neutral. This neutron does not contribute to the formation of charges.

Thus, neutrons are particles that have no charge.

Therefore, the given statement is false.

This bombardier beetle is spraying a boiling hot liquid that contains irritating chemicals, used as a defense mechanism against its enemies. The beetle stores two sets of chemicals separately in its glands. Using what you learned about chemistry in this chapter, propose a possible explanation for why the beetle is not harmed by the chemicals its stores and what causes the explosive discharge.

While waiting at an airport, Neil Campbell once overhead this claim: it鈥檚 paranoid and ignorant to worry about industry or agriculture contaminating the environment with their chemical wastes. After all, this stuff is just made of the same atoms that were already present in our environment.鈥� Drawing on your knowledge of electron distribution, bonding and emergent properties (see Concept 1.1), write a short essay(100-150 words) countering this argument.

The percentage of naturally occurring elements making up the human body (see table2.1) is similar to the percentage of these elements found in other organisms. How could you account for this similarity among organisms?
