Essentially all of the mass of an atom is due to the ______.(A) electrons.(B) neutrons.(C) nucleons.(D) protons.

Answers

Answer 1

Answer:

Answer:

Atom is made up of NUCLEUS and electrons revolving around nucleus.

Nucleus itself contains protons and neutrons. Protons and neutrons are approximately 1680 times heavier than the electrons. So the major contribution to the mass of an atom comes from the nucleus.

Answer 2

Answer:

Final answer:

The mass of an atom is mostly carried by the nucleons, protons, and neutrons, in its nucleus. Electrons contribute very little to the overall mass of an atom because of their small mass.

Explanation:

Essentially, all of the mass of an atom is due to the nucleons. An atom is primarily composed of protons, neutrons, and electrons. However, the mass of an electron is so small that it contributes very little to the overall mass of an atom. The term 'nucleons' refers to the particles in the nucleus of an atom, namely the protons and neutrons. These particles carry most of the atom's mass given their relatively large mass compared to electrons.

Radiometric isotope x decays to daughter isotope y with a half-life of 220,000 years. at present you have 1/4 gram of x in the rock. from the amount of daughter isotope y presently in the rock, you determine that the rock contained 16 grams of isotope x when it formed. how many half-lives have gone by? how old is the rock?

Answers

The amount left after 1 half life = 16*1/2 = 8 g Then after each half life the amount of x will be 4 , 2 ,1 , 1/2, 1/4 grams

That's a total of 6 half-lives. Answer

A substance with a high vapor pressure at normal temperatures is often referred to as volatile. As the temperature of a liquid increases, the kinetic energy of its molecules also increases and as the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.

Answers

As the temperature of a liquid or stable will increase its vapor strain additionally will increase. Conversely, vapor strain decreases because the temperature decreases.

The better the vapor strain of a substance, the extra the awareness of the compound withinside the gaseous section and the extra the quantity of vaporization

. Liquids range substantially of their vapor pressures. substance with a excessive vapor strain at everyday temperatures is regularly called volatile. The strain exhibited through vapor gift above a liquid floor is referred to as vapor strain. As the temperature of a liquid will increase, the kinetic strength of its molecules additionally will increase.
