the atomic weights on the Periodic Table
It is the lightest element.
all atoms are generally the same size, so "large atoms" would mean molecules.
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
Gold is a "Noble Metal", which means its atoms do not readily share electrons with atoms of other elements.
because some atoms are bigger than others
the atomic weights on the Periodic Table
The atomic mass of an element tells you how heavy its atoms are compared with atoms of other elements. Atomic mass is the average mass of an atom of an element, taking into account all its isotopes and their abundance.
It is the lightest element.
the atom is an isotope
Yes given enough time
Yes, platinum is heavy compared to other metals.
Silver is considered a heavy metal in terms of its density compared to lighter elements like oxygen or carbon. However, it is not as heavy as some other metals like gold or platinum.
No it's the other way around. Elements are made up of atoms.
Apart from the inert gases which are monoatomic all of the other elements bond to themselves and to atoms of other elements.
when they are in contact
all atoms are generally the same size, so "large atoms" would mean molecules.
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
