1. Sodium is the least abundant alkali metal. 2. Sodium is the most common positive ion in the fluid outside cells. 3. Sodium is found in table salt. 4. Sodium is used in vapor lamps and produces a yellow-orange color.

What is 1)Sodium is the least abundant alkali metal. ? (Sodium is actually the MOST abundant alkali metal.) Click Anywhere to Continue

1.Nitrogen is colorless, odorless, and fairly reactive. 2. Compounds of nitrogen are often found in explosives such as TNT and nitroglycerin. 3. Boron is found in borosilicate glass, which is known for its strength. 4. Boron nitride is used as a superabrasive.

What is 1)Nitrogen is fairly reactive. ? Nitrogen is relatively UNreactive (which makes sense being the main component of our atmosphere.) Click Anywhere to Continue

1)Hydrogen has three isotopes – protium, deuterium, and tritium. 2) Hydrogen is flammable. 3) Hydrogen can form +1 or -1 ions. 4) Hydrogen is part of the alkali metal family.

What is 4)Hydrogen is part of the alkali metal family. ? (Hydrogen is in a family by itself.) Click Anywhere to Continue

1. Lead is toxic. 2. Lead used to be used as an additive to paint. 3. Lead is currently used in storage batteries. 4. Mercury exists as a silvery solid. 5. Bromine exists as a red- brown liquid.

What is 4)Mercury is a solid ? (Mercury is a liquid.) Click Anywhere to Continue

1. Most lanthanides are phosphors. 2. Most actinides are present in nature, but only in small amounts. 3. Transition metal compounds often form colored solutions. 4. Radon is a gas which is dangerous to inhale.

What is 2)Most actinides exist in nature ? (Only 3 exist. Most are synthetic.) Click Anywhere to Continue

This diatomic gas makes up ~20% of our atmosphere.

What is Oxygen? Click Anywhere to Continue

This diatomic gas makes up 80% of our atmosphere.

What is Nitrogen? Click Anywhere to Continue

This metal is not found uncombined in nature. It is found in in batteries and in a drug used for bipolar disorder.
