What is period on the periodic table?

Answer 1

• Horizontal rows
• Organize elements according to their atomic number

Question 2

What is a group of the periodic table?

Answer 2

• Vertical columns
• Organize elements according to the number of valence electrons they possess

Question 3

Answer 3

• Left of the stair case

Question 4

Where are nonmetals found on the periodic table?

Answer 4

• Right of the staircase

Question 5

Where are metalloids found on the periodic table?

Answer 5

• They border the staircase

Question 6

What are the properties of Metals?

Answer 6

State
- Solids at room temperature
Appearance
- Shiny, luster
Conductivity
- Good conductors
Malleable/Ductile
- Very malleable and ductile

Question 7

State
- Some gases, some solids
Appearance
- Not shiny
Conductivity
- Bad conductors
Malleable/Ductile
- Brittle, not ductile

Question 8

What are the properties of metalloids?

Answer 8

State
- Solids at room temperature
Appearance
- Can be shiny or dull
Conductivity
- Some good, some bad conductors
Malleable/Ductile
- Brittle, not ductile

Question 9

What is an alkali metal, and where is it found?

Answer 9

• Extremely reactive
• Rarely found in pure form because of how easily they react with other elements
• Found in group 1

Question 10

What is an alkaline earth metal, and where is it found?

Answer 10

• Less reactive than alkali metals
• Found in group 2

Question 11

What is a Noble gas, and where is it found?

Answer 11

• Non reactive elements
• Found in group 18

Question 12

What is a Halogen, and where is it found?

Answer 12

• Extremely reactive
• Gases at room temperature
• Found right on the black line

Question 13

What is the electron dot diagram?

Answer 13

• Electron dot diagram, or “Lewis diagrams”, is used to show the number of valence electrons an atom possesses. Elements with unpaired electrons are capable of reacting with other elements. Those with a single unpaired electrons are typically more reactive than those with with multiple unpaired electrons.

Question 14

What is the characteristics of physical properties?

Answer 14

• A physical property is any property that can be observed or measured without forming a new substance.
• Color, texture, state, malleability, smell, boiling point, density, viscosity, solubility, conductivity, mass

Question 15

What are the characteristics of chemical properties?

Answer 15

• Chemical properties are any property that describes how a substance reacts with another substance.
• Reactivity, combustibility, stability, enthalpy of formation, pH(acidity/basicity), toxicity
