Two elements that have atoms of very different sizes means that the cast iron is likely a substitutional alloy.
Gold is a "Noble Metal", which means its atoms do not readily share electrons with atoms of other elements.
If atoms didn't have electrons then you wouldn't be asking this question. No electrons means no elements, no elements mean no building blocks for life or basically anything, no anything means nothing. we'd all die.
Atoms of elements in group (column 2 of the periodic table) have 2 electrons in their outer shell. They have a low electronegativity, which means the electrons are not strongly attracted to the protons in the nucleus when compared to the electrons in atoms of column 6 or 7. For this reason, group 2 elements easily form +2 ion when in the presence of group 6 or7 elements.
C6H12O6 (six atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen making it a carbohydrate, because of carbon, hydrogen, and oxygen
Fission is a splitting apart. Fusion is a putting together. You get energy by splitting heavy elements AND by fussing light elements. The mid point is iron, the element with the least amount of available "nuclear" energy ... thus it is the ultimate ash from any nuclear reaction.
Different atomic numbers represent different elements.

elements have unique sets of properties
NO!!! 'diatomic' means two atoms. There are four atoms in H2O2 so it could be referred to as 'tetratomic;,

Atoms: smallest unit of an element. Molecule: smallest unit of a compound., combination of atoms of the same or different elements., a group of atoms chemically bonded together. Both: divisible by chemical or nuclear means, smallest unit that can be isolated through physical changes.

2 and they are hydrogen and oxygen H20 means their are 2 hydrogen atoms, and 1 oxygen atom
No: A full valence shell means the atom is very stable and has little likelihood of combining with other atoms.
There are 3 carbon + 8 hydrogen + 1 oxygen = 12 atoms..!!
Elements are composed of the same atomic atoms/molecules. This means that every particle in an element has the same number of protons in the nucleus.
