What makes an atom a good conductor?

1 answer:

3 0

Very little electric force is required to cause electron flow in conductors. This is due to electrons called "free electrons", which exist in the atoms of conductors. "Free electrons" are electrons that are very weakly bonded to the atom. ... Metals such as copper, silver, and gold are good conductors.

Well, atoms are loosely bound and free to move through the material. Almost all, or just most, atoms will hold on to electrons very tightly and are insulators.

An element forms a negative ion when ionized. what side of the periodic table is it located on?

Zina [86]

<span>Mendeleev's periodic table was in error because when the elements were arranged by mass it resulted in several elements being placed in groups of elements with differing properties.</span>

Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in

igor_vitrenko [27]

Explanation:

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

When oxidizing agent-A get reduced it changes green to colorless.

$A+e^-\rightarrow A^-$

When oxidizing agent-B get reduced it changes yellow to colorless.

$B+e^-\rightarrow B^-$

When oxidizing agent-C get reduced it changes red to colorless.

$C+e^-\rightarrow C^-$

1) When we added solution C that oxidizing agent-C in solution containing $B^-$ ions changes from red to yellow:

$C+B^-\rightarrow C^-+B(yellow)$

So, in this C is oxidizing $B^-$ ion into B which yellow in color.

C is reduced and $B^-$ ions is oxidized.

Here, $B^-$ are oxidized by C which means that C a better oxidizing agent than B.

2) When a solution of C is mixed with one containing A- ions, the color remains red.

$C+A^-\rightarrow$ no reaction

As we had observed that no color change was seen on adding substance C to the solution with $A^-$ ions which indicates that C was unable to oxidize $A^-$ ions. Hence, not a better oxidizing agent than A
