Suppose a star is undergoing a nuclear reaction. What happens to the elements around the star as it begins to emit more and more

electromagnetic radiation? The lighter elements are pushed farther away than the rocky materials. The rocky materials are broken down into smaller particles. The rocky materials are pulled in by the electromagnetic radiation. The lighter elements are burned up by the electromagnetic radiation.

I think the correct answer would be the third option. As the elements around the star begins to emit more and more electromagnetic radiation, the rocky materials are pulled in by the electromagnetic radiation. They are being drawn closer to the star and there would be a very high chance of a nuclear fusion could happen. The pressure and the temperature in a star is so high that it could allow nuclear fusion to happen. As a matter of fact, most of the life of a start is made from hydrogen nuclei fusing together forming a helium nuclei. As it runs out of the hydrogen nuclei, it would fuse other nuclei forming other elements.<span />

Explanation:

The faster particles move, the more kinetic energy they have. Within a given substance, such as water, particles in the solid state have the least amount of kinetic energy. Particles in the liquid state move faster than particles in the solid state. Therefore, they have more kinetic energy.

describe the trends in the atomic size, location energy and electrongavity from left to right across a period in periodic table
Elenna [48]

Atomic size decreases in a period but the ionization energy and electronegativity increases across a period.

<h3>Describe the trends in the atomic size, ionization energy and electronegativity?</h3>

Atomic radius decreases across a period because of nuclear charge increases whereas atomic radius of atoms generally increases from top to bottom within a group because there is again an increase in the positive nuclear charge.

Ionization energy increases when we move from left to right across an period and decreases from top to bottom.

Electronegativity also increases from left to right across a period and decreases from top to bottom.

So we can conclude that atomic size decreases in a period but the ionization energy and electronegativity increases across a period.

A nugget of GOLD has a mass 9.66 gram and a volume of 0.5 cm3, It's density is<br>grams/cm3 *​
dalvyx [7]

Answer:

P=19.32g/cm³

Explanation:

m=9.66g

v=0.5cm³

P=mass/volume (density formula)

=9.66/0.5

=19.32g/cm³

What effect does supercritical mass have on a nuclear reaction?
Ksju [112]
Supercritical mass results to an increase in the rate of fission. There is a chain reaction that will occur. Nuclear fission or explosion used in atomic bombs relies on supercritical mass. An atom splits into two, with each splitting into two pairs and so on, releasing energy in each step.
