Matter/Solutions
Matter is anything that has ____________.
What is mass?
These three particles make up an atom
What are the proton, neutron & electron?
Electrons are located in this part of the atom
This tells you the order the element is listed in
What is the atomic number?
Ions are atoms or groups have atoms that have this
What are electric charges?
Breaking a ruler in half is an example of this type of change
What is physical change?
The atomic number tells you the number of _______ an element has
What are protons?
Electrons move around the nucleus in this motion
What is orbit?
The big letter or letters in the middle of each element
What is chemical symbol?
This prefix lets you know there are multiple atoms in the ion
What is poly- (polyatomic)
Metal rusting after exposure to oxygen over a long period of time is an example of this type of change
What is chemical change?
The mass of an atom is made up almost entirely from the ________ & __________.
What are protons & neutrons?
The outermost electrons, which are important because they determine how an element reacts
What are valence electrons?
The bottom number on an element listed in the periodic table
What is atomic mass?
The net charge for an ion with 12 protons and 14 electrons would be this
What is -2?
Pure Substances are either _________ or __________
What are elements or compounds?
Subtracting the atomic number from the atomic mass tells you the number of this particle
What are neutrons?
The number of valence electrons an element has can be found by looking at this part of the periodic table
What is the group?
What is the top-right?
The net charge for an ion with 11 protons and 7 electrons would be this
What is +4?
This type of matter can either be homogenous or heterogenous
What is a physical mixture?
When two things are made up of the exact same element yet are different substances due to their atomic structure
What are allotropes?
The number of electron layers an element has can be determined by looking at this part of the periodic table
What is the period?
Atomic size does this as you move down a group
This atomic particle is the one being gained or lost when an ion is formed
What are electrons?
