## Is a diagram a mental picture or object that helps explain ideas about the natural world?

In science, a model may be a diagram, a mental picture, a mathematical statement, or an object that helps explain ideas about the natural world.

### What two particles account for almost all of the mass of an atom quizlet?

What two particles account for almost all of the mass of an atom? Protons and neutrons count for almost all mass of an atom.

Why is it difficult for us to study the atom quizlet?

Why is it difficult to measure the size of an atom? it is difficult to measure the size of an atom because it is very small.

What three particles are found in an atom quizlet?

Protons, neutrons, and electrons are the three main subatomic particles found in an atom.

## Where are these parts located in an atom?

Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.

### What two particles make of almost all of the mass of an element?

Neutrons and protons constitute almost all of an atom’s mass. The third type of stable particle is the electron. Electrons have a negative charge but are extremely small and have a mass only 1/1850 that of a proton or neutron. They are so small that for practical purposes they do not contribute to the mass of the atom.

Which two particles account for almost all the mass of an atom?

The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus.

What three particles are found in an atom?

There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.

## Do particles touch?

Particles are, by their very nature, attracted to particles with an opposite charge, and they repel other similarly charged particles. This prevents electrons from ever coming in direct contact (in an atomic sense and literal sense). Their wave packets, on the other hand, can overlap, but never touch.

### How could you use a red blue and yellow marbles to model a carbon atom?

Review 5)How could you use red, blue, and yellow marbles to model a carbon atom? Arrange yellow and blue in the center as proton and neutron while red as electrons revolving in a different shell. Explanation: Carbon atom; 6 protons=6 neutrons present in nucleus of atom + 6 electrons in the shell.

How is math used to describe the Book of nature?

“Math is our one and only strategy for understanding the complexity of nature,” says Ralph Abraham, a mathematician at the University of California Santa Cruz, in NOVA’s Hunting the Hidden Dimension. “Fractal geometry has given us a much larger vocabulary, and with a larger vocabulary we can read more of the book of nature.”

Is the natural world all around us all the time?

It may seem like we live entirely in a man-made world. Cities, towns, homes, schools, cars, roads, and computers are all made by man. But the natural world is all around us, all the time. The earth is under those cities and towns. We breathe the air and drink the water that come from the natural world.

## How is Galileo’s formula used to describe nature?

Galileo’s succinct formula neatly expresses the notion of acceleration of objects near the surface of the Earth, but that is just the start of its usefulness. First, just as with any value of t you can calculate d, for any value of d you can figure t.

### How is math related to the way the universe works?

“Just as music is auditory patterns that the human mind finds pleasant,” says Stanford mathematician Keith Devlin, “mathematics captures patterns that the universe finds pleasant, if you like—patterns that are implicit in the way the universe works.” “Einstein used mathematics to see a piece of the universe that no one had ever seen before.”
