The answer is C : Radioactive dating. I know this because radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the fossil, organism, and/or material.
C. seaborgium: atomic number 106, mass 266, neutrons 160
Explanation:
An atom is made up three fundamental particles:
- Protons are the positively charged particles in an atom
- Electrons are the negatively charged particles
- Neutrons carry no charges.
The mass number is the sum of protons and neutrons in an atom because they contribute to the mass of an atom.
The atomic number is the number of protons in an atom. For a neutral atom, it is the same as the number of electrons.
Number of neutrons = mass number - atomic number
For seaborgium,
Number of neutrons = 266 - 106 = 160
This is the only correct option given.

<h2>
Simple diffusion is defined as the movement of: A molecules from areas of higher concentration to areas of lower concentration.</h2>
Explanation:
Diffusion
It is the movement of substances from the region of higher concentration to lower concentration .
This diffusion is shown almost negligible by solids , a little by liquids and maximum by gases .
The factors on which diffusion depends :
- Inter-molecular force between particles : It is inversely proportional to diffusion .That is : more is the force , lesser the diffusion rate
- Inter-molecular space between particles : More is the space , more is the diffusion or vice versa .
- Density of substance :More is the density , less is the diffusion or vice versa .
Applications of diffusion
It helps in the movement of substance in and out from the cell and its components .
It helps in spreading the fragrance when sprayed with some perfume etc .
It helps in dissolving substance in any medium
Etc
