Atoms/Molecules 1
All matter consists of what particle?
All matter consists of atoms.
What is a Nucleus made up of?
Protons and neutrons
What element has no neutrons?
Hydrogen.
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
Is dihydrogen monoxide toxic?
No. It's water.
Which is more reactive Helium or Fluorine?
Fluorine because the outer shell is very close to complete.
Why must there always be an equal amount of protons and electrons?
They help hold each other in place, like a magnet.
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.
What element has the Atomic Number of 80?
Mercury (Hg)
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.
Na and Cl combine to make what molecule?
Table salt.
Which is the smallest of the three subatomic particles?
Electrons
When is an element most reactive?
The closer the outer shell is to full or empty. When there is only 1 or 7 electrons in the outer shell.
What's the opposite of a subscript?
Superscript
Can all atoms connect with each other?
No, only atoms that have space available.
For example on its outer shell, can join other atoms. Like oxygen There are a total of 8 electrons. Two of those electrons fit in the first ring. That means 6 fit in the second ring. The second ring holds up to 8 electrons, leaving 2 spaces available.
How many atoms are in CH20?
There are four atoms
Atoms can be formed to combine ________ through chemical reactions.
Molecules
How do Na and Cl bond?
Cl takes an electron from Na. Ionic bond.
