Groups of Elements in Periodic Table

• What are Group 1 elements known as?

  Alkali Metals
• How does reactivity change as you go down Group 1?

  Reactivity increases as the atoms get larger.
• What happens when Alkali Metals react with water?

  They release hydrogen and form hydroxides.
• What do Alkali Metals form when they react with non-metals?

  They form ionic compounds.
• Why are Alkali Metals stored under oil?

  To prevent reactions with moisture and air.
• What is the general appearance of Alkali Metals?

  Shiny and soft, and often silvery-white.
• What happens to the outer electron in Alkali Metals?

  It is easily lost, making them highly reactive.
• What are Group 2 elements known as?

  Alkaline Earth Metals
• How does reactivity change as you go down Group 2?

  Reactivity increases as you move down the group.
• What happens when Alkaline Earth Metals react with water?

  They release hydrogen and form hydroxides.
• What is the general appearance of Alkaline Earth Metals?

  Shiny, silvery metals that are harder than Alkali Metals.
• What do Alkaline Earth Metals form when they react with non-metals?

  They form ionic compounds, often with halogens.
• What is the trend in the melting points of Alkaline Earth Metals?

  Melting points generally decrease as you go down the group.
• What happens when Magnesium (Mg) reacts with water?

  Magnesium reacts slowly with cold water but quickly with steam.
• What happens when Calcium (Ca) reacts with water?

  Calcium reacts more vigorously with water, forming calcium hydroxide.
• What are Group 7 elements known as?

  Halogens
• What is the trend in reactivity as you move down Group 7?

  Reactivity decreases as you go down the group.
• What happens when Halogens react with metals?

  They form ionic salts.
• What happens when Halogens react with hydrogen?

  They form hydrogen halides, which are often acidic.
• What is the general appearance of Halogens?

  They are colorful, diatomic molecules.
• What are the states of matter for Halogens at room temperature?

  Fluorine: gas, Chlorine: gas, Bromine: liquid, Iodine: solid.
• What happens when Chlorine (Cl2) reacts with water?

  It forms hydrochloric acid and hypochlorous acid.
• What happens when Iodine (I2) is placed in a solution of potassium iodide?

  It displaces the iodine from the potassium iodide and turns the solution brown.
• What are Group 0 elements known as?

  Noble Gases
• What is a key property of Noble Gases?

  They are inert due to having a full outer shell.
• What happens to the boiling points of Noble Gases as you move down the group?

  Boiling points increase as you go down the group.
• What is the general appearance of Noble Gases?

  They are colorless, odorless gases.
• What are some common uses of Noble Gases?

  Helium is used in balloons, Neon in signs.
• Why are Noble Gases used in light bulbs?

  They are inert and prevent the filament from reacting.
• What is the trend in atomic size for Noble Gases?

  Atomic size increases as you move down the group.
• What are Transition Metals?

  Elements found in Groups 3-12 of the periodic table.
• What is a key property of Transition Metals?

  They are good conductors of heat and electricity.
• What is a characteristic of Transition Metals’ reactivity?

  They have moderate reactivity and are less reactive than Group 1 and 2 metals.
• What happens to Transition Metals' melting points as you go down the group?

  Their melting points are generally high, but decrease slightly.
• What is a common use of Transition Metals?

  They are used in construction and electrical components.
• What is the appearance of most Transition Metals?

  They are shiny and often have a metallic luster.
• Do Transition Metals form colorful compounds?

  Yes, many Transition Metals form colorful compounds.
• What are Group 13 elements known as?

  Boron Group
• What are Group 14 elements known as?

  Carbon Group
• What are Group 15 elements known as?

  Nitrogen Group
