Study Notes
Elements
- Silver (Ag) is a pure element, consisting of one type of atom; found on the periodic table with its unique atomic number.
- Gold (Au) is categorized as an element due to its single type of atom and presence on the periodic table.
- Copper (Cu) is recognized as an element with one type of atom and a designated atomic number, appearing in items like pennies.
- Helium (He) is an elemental gas found in balloons, characterized by a single type of atom and listed on the periodic table.
- Aluminum (Al) is an element seen in foil, recognized for having only one type of atom.
- Lithium (Li), found in batteries, is distinguished as an element; it possesses a unique atomic number among elements.
- Mercury (Hg) is an element used in thermometers, consisting of one kind of atom without bonding.
- Neon (Ne) is an elemental gas present in advertising signs, featuring only one type of atom.
- Nickel (Ni), found in coins, qualifies as an element due to its atomic singularity and periodic table classification.
- Iron (Fe) from nails is categorized as an element with just one type of atom and listed atomic number.
