Question 1

What is and Ion?

Answer 1

An atom with a charge that has the wrong number of electrons.

Question 2

What is a Cation?

Answer 2

An element that loses electrons to become positive. (PAW-sitive)

Question 3

What is an Anion?

Answer 3

An element that gains electrons to become negative.

Question 4

What is the Atomic Radius?

Answer 4

The radius of the atoms of the atom from the nucleus to the outermost ring.

Question 5

What direction of the periodic table is when the Atomic Radius decreases?

Answer 5

To the right

Question 6

What does it mean when you add more electrons and protons to an atom?

Answer 6

The greater attraction the atom gets. which pulls the valence ring in closer to the nucleus.

Question 7

What direction do you go in the periodic table in order for the Atomic radius to Increase?

Answer 7

Go down the periodic table.

Question 8

What does adding more electrons to the valence ring do to an atom?

Answer 8

Adding more electrons to the valence ring pushes the ring further out from the nucleus.

Question 9

What is Electron Affinity?

Answer 9

The amount of energy released when an atom gains an electron. It increases and you move up and to the right of the periodic table.

Question 10

What is the Shielding Effect?

Answer 10

Electrons that are on the outermost rings block the effects of the nucleus pull, so more interior electrons means less attraction.

Question 11

What is Ionization energy?

Answer 11

The amount of energy required to remove a valence electron and form a Cation.

Question 12

What directions do you go when the Ionization energy increases?

Answer 12

You move up and to the right.

Question 13

What makes it harder to pull an electron free?

Answer 13

When the valence ring moves in closer which requires more energy

Question 14

A proton is responsible for what is an atom?

Answer 14

The proton is responsible for the Identity of an element.

Question 15

How does the number of valence electrons relate to an elements placement on the periodic table?

Answer 15

By the group or column that the element is in.

Question 16

How does the number of energy levels in an atom relate to where it is on the periodic table?

Answer 16

the periods or rows that an element is in.

Question 17

What does the neutron do in an atom and where is it located ?

Answer 17

The neutron stabilizes the atom and determines the mass. It is located in the nucleus of an atom.

Question 18

What kind of bond do metals and non metals make?

Answer 18

An Ionic bond

Question 19

How can you tell is a compound will form a covalent bond?

Answer 19

If both are non metals and they don’t have full valence

Question 20

What is the purpose of the sea of electrons in a metallic bond?

Answer 20

The sea of electrons holds together the atoms

Question 21

How many valence electrons does carbon have? (periodic table)

Answer 21

4 valence electrons

Question 22

What makes Noble Gases different from the other groups on the periodic table?

Answer 22

The Noble Gases have full valence which makes them non reactive.

Question 23

What kind of elements have high luster?

Answer 23

Metals

Question 24

Why are Metaloids considered to be semi-conductors? What does it mean?

Answer 24

Because their property is half metal and half non-metal. They can conduct.

Question 25

What type of element do you use if you need to insulate something?

Answer 25

You use a Non- metal

Question 26

When an electron is hit by a wave of electromagnetic energy, what can happen to that electron?

Answer 26

The electron would want to jump up to a higher energy level

Question 27

Why does an atom want to move back down when it's above ground state?

Answer 27

The electron is unstable if not in the ground state and wants to go back down in order to be stable.

Question 28

When an electron drops back down to the ground state, it releases energy. As the distance of the drop increases, how does that affect the energy of electromagnetic wave that it emits?

Answer 28

If the drop is father the higher the energy. I the drop is less the less energy is takes.

Question 29

If I want a solid solute to dissolve quickly, what should I do to the temperate of my solvent?

Answer 29

Raise the temperature (usually)

Question 30

If I need a solid solute to dissolve quicker, what can I do to the solute itself before mixing it in?

Answer 30

You can make the crystals smaller.

Question 31

If a solution has a lot of solute dissolved into it, how will that affect the rate of dissolving if I add even more solute?

Answer 31

If the solute has high concentration then the solute will dissolve slowly

Question 32

Are the properties of the reactants and products the same in a chemical reaction? Why or why not?

Answer 32

The properties and reactants are NOT the same because you have created a new substance.

Question 33

If you mix two chemicals to form a solution and bubbles begin to form, what does that mean what's happening in the beaker?

Answer 33

There is a chemical change that is happening. You are producing a gas which is a new substance.

Question 34

What is it called when you mix two liquids and solid particles form and fall to the bottom of the container? what does this indicate?

Answer 34

The liquids precipitate...

Question 35

Why is Magnesium to the right of Sodium on the Periodic Table ?

Answer 35

Because Magnesium has 1 more electron than Sodium

Question 36

What makes the alkali metal, potassium, so reactive?

Answer 36

It has 1 valence electrons and it's eager to get rid of that 1 valence electrons to have full valence or be inert.

Question 37

How does the size of an atom change as you move across a periodic table?

Answer 37

They get smaller
