Answer:
7.69x
Explanation:
The ionization is the energy necessary to transform an atom in an anion. So, it's the energy it requires to gain an electron.
This ionization occurs for the photoelectric effect - the emission of electrons by metal using photons. So, if the efficiency is 100%, 1 photon can ionize 1 atom, but for an effficiency of 13.0%:
N = 
N = 7.69x
Where N is the number of photons.
Answer:
Sodium (Na)
because it belongs to the first group of the periodic table. Therefore its properties are similar to that of lithium.
<span>'It is formed when metal atoms lose electrons to nonmetal atoms' is the incorrect statement. This statement is the definition of ionic bonding.

Answer:
Alkenes have substituents, hydrogen atoms attached to the carbons in the double bonds. The more substituents the alkenes have, the more stable they are. Thus, a tetra substituted alkene is more stable than a tri-substituted alkene, which is more stable than a di-substituted alkene or an unsubstituted one.
