Metals have fewer protons in their nucleus compared to nonmetals, meaning their electrons are held less tightly by the positively charged nucleus. This results in lower ionization energies for metals, making it easier to remove electrons from them compared to nonmetals. Additionally, metals tend to have more outer electrons which are further away from the nucleus, making them easier to remove.
Humans had learned to make tools of chipped stone, but had not yet learned to make them from metals.
Because capsare made of metals, and when metals get hot they expand, making it bigger, and easier to unscrew
Cheaper higher quality metals became available during the Industrial Revolution.

He was born a slave in Maryland, around 1830 but became an inventor. He learned to read and write from his master child when it was against the law to teach a slave to read and write. When he was a teen, he made a steam machine out of scrap metals.
A forge traditionally is a place where metals are shaped and worked. Heated metal are softer, and can be shaped more/easier. The fire is used to heat the metals.
group 1A on the periodic table? that should be the alkali metals. i just learned that in class. lol.
civilized.

Alkaline earth metals have two outer electons. Alkali metals have one. It is more energetically favorable (easier) t oremove one electron than two making alkali metals more reactive than alkaline earths.
