Are whales made of atoms?

Both the whale and its surroundings are composed of matter. An understanding of atoms will enable the scientist to understand the whale and its habitat better.

What atoms are in every living thing?

The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N), which together make up about 96\% of the human body. In the nonliving world, elements are found in different proportions, and some elements common to living organisms are relatively rare on the earth as a whole.

How do we know what atoms look like?

Scanning tunnel microscopes are certainly able to give us some idea of what atoms look like and results that have been published declare these atom shapes to be perfectly spherical. Today the perfecting of attosecond lasers actually enable to see the orbit of an electron within an atom.

How do you know which atom is the largest?

There are 92 naturally found atoms — or elements — on earth. The largest atom, which has 92 protons with 92 electrons orbiting around them, is uranium. Each element is given an atomic number indicating how many protons and electrons that atom has.

How do you excite an atom?

5 Answers. You can excite an atom to a higher energy level in three ways – absorption, Raman scattering and atomic collisions. The simplest method is to shine light (photons) of the right energy at the atom. Some of these photons will get absorbed by the atoms and cause transitions to the said higher level.

How do I make a model of an atom?

Assemble the Atom Model. The nucleus or core of each atom consists of protons and neutrons. Make the nucleus by sticking protons and neutrons to each other. For a helium nucleus, for example, you would stick 2 protons and 2 neutrons together. The force that holds the particles together is invisible.
