Almost. Cents made from 1864 to 1942 and from 1944 to mid-1982 were made of approximately 95% copper and 5% other metals, mainly tin and/or zinc. 1943 cents were of course made of steel due to WW2 metal needs.
To find a pure copper cent you'd have to go back to the days of Large Cents, before 1857.
A post-1982 penny is made of 97.5% zinc and 2.5% copper. The composition changed from primarily copper to primarily zinc in order to reduce production costs.
If the penny was made pre-1982, it weighs 3.11 gm and is made of bronze containing 95% copper. That means it contains 0.95 * 3.11 = 2.955 gm of pure copper. If the penny was made post-1982, the penny will weigh 2.5 gm and be made of 97.5% zinc with a coating of copper, so it only contains 0.025 * 2.5 = 0.0625 gm of pure copper.
No not anymore starting in 1982 Lincoln cents are made of 97.5% ZINC and 2.5% copper
No. In Canada, they are 99.9% copper and 0.1% silver. I am not sure what it is in the USA so go to the mint.
A 1984 penny is made of 97.5% zinc and 2.5% copper. Since 1982, the composition of pennies in the United States changed to primarily zinc with a thin copper coating.
No. Pennies made before 1982 were 95% copper, with 5% zinc.
1982. before that, a penny was made up by 95% copper (Cu) and 5% zinc (Zn) and/or tin (Sn). A penny made after mid-1982 is 2.5% Cu and 97.5% Zn!
You can tell if a penny is made out of zinc or copper by the date on the penny. If the date is before 1982 then the penny is 95% copper. Pennies dated 1983 or later are 97.5% zinc with a thin copper coating.
No. A penny is made out of copper-plated zinc.
If by formula you mean composition, a post-1982 penny is 97.5% Zinc and 2.5% Copper by mass.
Since 1982, it's been made of 97.5% zinc with 2.5% copper for plating. Before that, it was 95% copper mixed with 5% zinc.

From 1783-1837, a penny was pure copper. But newer pennies are made mostly of zinc.He is tottaly right

The metal composition of penny coins made after 1982 is 97.5 percent zinc and 2.5 percent copper. The first penny coins, from 1793 to 1837, were made from pure copper.
