A scientist was working in a nuclear reactor facility and was exposed to radioactive particles. Although the scientist was wearing only basic clothing as protection, she exhibited no symptoms of radiation poisoning. What type of radiation was the scientist most likely exposed to? Group of answer choices

A. Beta

B. Gamma

C. Alpha

D. None of the above

C. Alpha

Explanation:

In a nuclear reactor facility, radioactive decay takes place, which is any several processes by which unstable nuclei emit subatomic particles and ionizing radiation and disintegrate into one or more smaller nuclei. A scientist working under this condition is likely to be exposed to alpha particles because it contains a minimal absorption range and they are the least dangerous regarding external exposure.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
