When a beta particle<span> is emitted from the </span>nucleus<span> the </span>nucleus<span> has one more proton and one less neutron. This means the </span>atomic<span> mass number remains unchanged and the </span>atomic<span> number increases by 1.
Best answer :
</span><span>b. the number of electrons in the atom increases by one as the beta particle leaves the nucleus and joins the valence electrons</span>
Earth orbits the sun in a imaginary plane called ecliptic
Answer:
b. changing the compound changes the absorbance behavior.
Explanation:
- Option a) would be akin to modifying the <em>path length</em>, b.
- Option b) would involve using a different solute, as such, there would be another <em>molar absortivity</em>, ε.
- Option c) would decrease the<em> concentration</em> (c) of the solute, which would explain why the absorbance would decrease as well.
Iodine is a group 7A element. The halogens form anions because of their high electronegativities, so Iodine is unlikely to form a cation.
