Neon-22
Depending on the type of notation the question wants but that is generic term for it.
Technetium, with atomic number (denoted Z) 43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive. The second-lightest exclusively radioactive element, promethium, has an atomic number of 61.
The metals are elements which have low ionization potential and can lose electrons easily
the other physical characteristics associated with them and hence with Aluminium are
a) they can conduct electricity in molten state, hence It would only conduct electricity if it were melted.
b) It could be stretched into a thin wire. It means it is ductile.
In case of given aluminium metal the correct answer is
it could be stretched to thin wire
