Which statement is true about a proton and an electron?

Chemistry

tatyana61 [14]3 years ago
5 0

Answer: (3) They have different masses and the same charges.

Explanation:

Atoms are mainly composed of three main types of particles (in fact there are more particles that are smaller and make up these main particles): electrons, protons and neutrons.

In the specific case of  <u>electrons</u> and <u>protons</u>, <u>both have the same charge, but electrons have the opposite sign</u>. This means a proton has an electric charge of  +1 and an electron has an electric charge of  −1.

On the other hand, <u>protons have more mass than electrons.</u> In fact, thetex]mass of an electron is about approximately \frac{1}{2000} the mass of a proton, this means these negative charged particles contribute almost nothing to the total mass of an atom (unlike protons, which together with neutrons, make up virtually all of the mass of an atom).

However, each atom that is electrically neutral has the same quantity of electrons as protons.

Yanka [14]

Answer:

A) coenzyme A

Explanation:

The NADH and FADH₂ are the energy rich molecules which are formed in the processes like glycolysis, TCA cycle and the fatty acid oxidation as they contain pair of electrons which have very high transfer potential.

As a result of the energy produced when these molecules transfer their electrons to the oxygen , ATP is generated by a series of electron carriers which collectively is called electron transport chain (ETC).

<u>The components of chain include Fe–S centers, Non-heme, FMN, coenzyme Q, and cytochromes . </u>

The energy derived from the transfer of electrons is used to pump the protons across mitochondrial membrane.

As a result, an electrochemical gradient is generated which results in some energy which is then harnessed by the ATP synthase to form ATP.

What are the two basic ways in which ions form from atoms?
andrew-mc [135]

Answer:

An ion is an atom or group of atoms that has an electric charge. When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron, it gains a negative charge and becomes a negative ion. a sodium ion forms when a sodium atom loses one electron and becomes positively charged. a chloride ion forms when a chlorine atom gains one electron and becomes negatively charged.

Hope this helps,
