What a matter is made up of?
The particles that make up matter are called atoms.
What are the three basic properties of matter?
The three basic properties of matter are volume, mass, and shape.
Where did the matter of the universe come from?
The Big Bang theory suggests that all the matter and energy in the universe exploded out from one point. As the explosion occurred, energy and matter spread outward and formed the universe. The matter from the Big Bang formed clouds of gas.
What are the properties of matter?
They include properties such as color, length, volume, odor, and density.
What is matter made of and why?
Matter is made of tiny little particles The particles that make up matter are called atoms.
What particles are in the nucleus?
Protons and neutrons
What are elements?
Elements are substances that cannot be separated into simpler substances.
What are the four states of matter?
solid, liquid, gas, and plasma.
How matter is divided?
pure substances and mixtures
Can an element be broken down into anything?
No
What is the measure of gravity on an object?
Weight is a measure of the force of gravity on an object.
Is an element matter?
Yes
Who said all matter is made up of atoms?
Democritus first suggested the existence of the atom but the atom was placed on a solid foothold as a fundamental chemical object by John Dalton
What are the positive particles in an atom?
Protons
What is the atomic structure of hydrogen?
One proton in the nucleus with an electron circling it
Are cells made up of matter?
Yes
Cells are composed of molecules, which are sets of atoms bonded together. Each atom, in turn, is an assemblage of elementary particles.
What attracts all objects to each other?
Gravity is a force that attracts all objects towards each other.
What is the difference between an atom and a molecule?
An atom is smallest particle in an element that has the properties of the element.
A molecule can be broken into atoms.
What are the particles in an atom without a charge?
Neutrons
What are the chemical properties of matter?
They include reactivity, flammability, and the ability to rust.
How matter can be classified?
All matter can be classified as either a mixture or a pure substance.
What is matter that has a definite shape and volume?
Solids have a definite shape and a definite volume.
What is the definition of atomic structure?
The definition of atomic structure is the positively charged nucleus and the negatively charged electrons circling around it, within an atom.
What is found in the nucleus of an atom?
Protons and neutrons
Do all objects attract each other?
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.
