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.

A metal rail rusting in damp weather.
He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.
