What is the difference between an atom and a compound?
Matter that is made up of only one type of atom. Compound Molecules that are made from different types of atoms, BUT always combined in the same proportions. Atomic Number
What is a mixture of different types of matter?
Matter that is a combination of different types of matter in different proportions. Element Matter that is made up of only one type of atom. Compound Molecules that are made from different types of atoms, BUT always combined in the same proportions. Atomic Number Indicates the number of protons found in an atom of a specific element.
What are the components that make up an atom?
Pieces of matter that make up atoms. Electron Negatively charged subatomic particle that circles the nucleus of an atom. Proton Positively charged subatomic particle that is a part of the nucleus. Neutron Neutral subatomic particle that is a part of the nucleus. Atomic Nucleus "Center" of the atom that is made up of protons and neutrons.
What is the center of an atom made of?
"Center" of the atom that is made up of protons and neutrons. Pure Substance Matter that is made of the same element or compounds. Mixture Matter that is a combination of different types of matter in different proportions. Element Matter that is made up of only one type of atom.
How many atoms are there in the world?
Everything in the world is made up from some combination of the 92+ different atoms that can exist. These 92+ types of atoms are called elements. Look up the Periodic Table to see what these elements are called.
Who proposed the word "atomos"?
In 400 BC a Greek philosopher named Democritus proposed the Greek word atomos which means uncut-able. And so as he explained all matter was eventually reducible to discrete,small particles or atomos.
What is the charge of a nucleus?
The neutrons and protons interchange gluons, particles that carry the strong nuclear force. A nucleus has an electric charge equal to its number of protons. That would be a powerful repulsive force flinging protons away if it weren’t for the strong nuclear force, which is many orders of magnitude more powerful. If the number of neutrons is sufficient and the atom has fewer than 26 protons (iron) it is stable.
Which particles carry the strongest nuclear force?
The neutrons and protons interchange gluons, particles that carry the strong nuclear force. A nucleu
Why does chemistry happen?
Chemistry happens because different atoms interact in different ways. This creates an incredibly complex situation, whereas you tried to imagine it was simple. But each little change is incredibly precise, like a
What can combine to form something simple or something very complex?
Combinations of different kinds of molecules can combine to form something simple or something very complex such as the human body.
What are you made of?
Obviously not. You, for instance, are made up of carbon, hydrogen, oxygen, sulfur, phosphorus, nitrogen, calcium, iron, and a few other kinds of atoms.
What are different versions of an element?
Different versions of an element. Atoms that have the same number of protons, BUT different number of neutrons.
What is a neutron subatomic particle?
Neutral subatomic particle that is a part of the nucleus.
