Atoms/Molecules 1
All matter consists of what particle?
All matter consists of atoms.
What is a Nucleus made up of?
Protons and neutrons
Which state of matter has neither a definite shape nor a definite volume?
Gas
Anything that has Mass and takes up space is known as?
Matter!
Where are electrons located in an atom?
Electrons are located on the outside of an atom. The protons keep the electrons in place.
True or False: An element contains only one atom and cannot be broken down into smaller parts.
This statement is TRUE
Which particle spins at an incredible rate outside of the atom?
Electrons
Which state of matter has a definite shape and a definite volume?
Solid
Is dihydrogen monoxide toxic?
No. It's water.
What element has the Atomic Number of 80?
Mercury (Hg)
Why can't you trust atoms?
Because they make up everything.
Describe a Proton.
A proton is a positively charge subatomic particle located in the nucleus at the center of an atom.
Which state of matter has no definite shape but a definite volume?
Liquid
Where do protons and neutrons clump together?
The nucleus
The Atomic Number represents what?
The number of protons and electrons
What does the number represent like in the molecule H2O?
The number represents how many atoms are represented, so there are two Hydrogen atoms.
What are the charges of each of the subatomic particles?
Protons are positive, electrons are negative, and neutrons have no charge.
Which state of matter has the fastest particles
Gas (Plasma also Counts)
Which is the smallest of the three subatomic particles?
Electrons
How many atoms are in CH20?
There are four atoms
What does the LEFT number represent in the chemical formula 3H2O
A campfire burns and smoke rises from the flame. What has happened to the molecules in the wood?
They broke apart and combined with oxygen to form new molecules
A puddle of water slowly disappears on a warm sidewalk. Which state change is taking place? What is causing the change?
Evaporation. Heat from the sun
What element has no neutrons?
Hydrogen.
Why is there usually an equal amount of protons and electrons in an atom?
They help hold each other in place, like a magnet. Making an atom stable
