<h2>Answer:</h2>

The most dense part of an atom is its nucleus. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus with a minimal contribution from the orbiting electrons.

Helium atom has two orbital electrons and two protons and two neutrons in nucleus. It has 4 atomic mass and 2 atomic numbers. So, the greatest concentration of atomic mass is in nucleus.

The greatest concentration of atomic mass is the atom's nucleus. This is because the nucleus is made up out of protons and neutrons while the electrons surrounding the nucleus have a very small mass.

Name the functional group in the<br> following molecule:
Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.

I need HELP!!!<br><br> Do the benefits of nuclear power outweigh the risks?
Georgia [21]
While there is no such thing as 100 percent safe, having nuclear energy is much safer than you think. It's thousands of times safer than conventional coal and other fossil-fuel-derived energy, not to mention the specter of environmental disaster from continued use of carbon-based energy sources.
