An aluminum nail that is less dense than the element aluminum would not be made of pure aluminum, but would have to be an alloy of aluminum and some other substance. If an aluminum nail is made of pure aluminum, it would have the same density as the "actual" element.
Gold or Au
Chlorine, with the atomic number 17 has one less proton than argon, with the atomic number 18
The answer is silicon.
an electron has way less mass than a proton.
The element aluminum can be found in the common household item, aluminum foil. This foil is usually less than half a millimeter in thickness.
Be is in the s block too. Li has one less proton than Be.
Hydrogen has one proton and one electron. Any less than that and you don't have an atom anymore.
Platinum(Pt) has 78 protons. Gold(Au) has 79 protons
A proton (or anti-proton).
The mantle has less aluminum and silicon than the crust does.
Bronze is not an element, it is an alloy (mixture) of copper and tin. Both are less reactive than aluminum.
In an element: yes Ions vary, like Ca+2 has two less electrons than protons.
No, aluminum is an element.
Nitrogen: The only atoms that have one less valence electron than the column 16 elements are those in column 15; of these, only nitrogen has a smaller atomic number than aluminum.
the mass of an electron is actually about 1800 times lessthan a proton.
The mass of an electron is about 1822 times less than that of a proton.
An electron weighs much less than a proton or neutron A proton or neutron weights about 1,800 times as much as an electron.
