(A) The statement “the atoms have more electrons than protons” is false.

(B) The statement “the atom has more protons than electrons.” is true.

(C) The statement “the atom has fewer protons than does a neutral atom of the same element” is false.

(D) The statement “The atom has more neutrons than protons” 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—increased 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.

In the term trace element, the adjective trace means that

(A) the element is required in very small amounts.

(B) the element can be used as a label to trace atoms through an organism’s metabolism.

(C) the element is very rare on Earth.

How many electrons does fluorine have? How many electron shells? Name the orbital that is occupied. How many electrons are needed to fill the valence shell?

The reactivity of an atom arises from

(A) the average distance of the outermost electron shell from the nucleus.

(B) the existence of unpaired electrons in the valence shell.

(C) the sum of the potential energies of all the electron shells.

(D) the potential energy of the valence shell.

Female luna moths (Actias luna) attract males by emitting chemical signals that spread through the air. Male hundreds of meters away can detect these molecules and fly towards their source. The sensory organs visible in the photograph are shown here. Each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. Based on what you learned in this chapter, propose a hypothesis to account for the ability of a male moth to detect a specific molecule in the presence of many other molecules in the air. What predictions does your hypothesis make? Design an experiment to test one of these predictions.
