Atoms & Matter
TRUE or FALSE: Everything except energy is made of matter and matter is made of atoms.
What is TRUE?
The study of matter.
What is chemistry?
What do chemical bonds do?
What is hold atoms together to form molecules or compounds?
Elements found on the LEFT side of the periodic table.
What is metals?
TRUE or FALSE: all elements on the modern day periodic table are naturally occuring.
What is false?
TRUE or FALSE: all atoms of the same element are the same.
What is true?
A charged particle.
What is an ion?
This type of bond forms between a metal and a nonmetal.
What is an ionic bond?
Usually malleable, able to conduct electricity, and shiny.
What are metals?
How many protons does an element with atomic number 17 have?
What is 17 protons?
The three parts of an atom.
What is proton, neutrons, and electrons?
Electrons on the outside of the electron cloud // the outermost electrons.
What is valence electrons?
This type of bond occurs between two nonmetals
This group of nonmetals is unreactive because it has a full valence shell.
What is the noble gases?
The unit we use when discussing atomic weights because pounds, grams or ounces would be WAY too big.
What is the atomic mass unit?
The part of the atom that hold the protons and neutrons.
What is the nucleus?
A covalently bonded compound.
What is a molecule?
This type of bond involves sharing electrons instead of transferring them.
What is covalent bond?
Elements that have some properties of metals and some of nonmetals.
What are the metalloids?
The chemist who predicted the discovery of two elements based on gaps in his proposed periodic table.
Who is Mendeleev?
The negatively charged subatomic particle that is most involved in reactions.
What is the electron?
This number tells how many protons + neutrons are in an atom.
What is the atomic number?
The strongest type of bond.
What is an ionic bond?
The only metal that is liquid at room temperature.
What is mercury?
How many neutrons does an atom with atomic number 12 and atomic mass of 24.3 have?
