Answer:
Chromium, calcium, and osmium
Explanation:
These elements are metals, considering this, these elements electron shells(orbitals) are further away from the nucleus, with this, their attractions are not as strong as non-metals, so some of their electrons are able to move freely.
When you accumulate many atoms, these metals can form a "sea of electrons" because they all have loose electrons interacting with each other. This allows easy conduction of heat and electricity.
N=9.933
Explanation:
no of mole = m÷mr
then ,no of molecules=n×la
It should be <em>Ultraviolet rays </em>because they are moderate in energy.
