Answer:
E)Li
Explanation:
Electronegativity is the tendency of an atom to attract a pair of bonding electrons. In the periodic table, electronegativity increases across the period and decrease down the group.
This means the element at the top of the group would have the highest electronegativity.
The correct option is;
E)Li
<span>explain why the dissolved component does not settle out of a solution -
</span><span>Before saturation, there are attractive forces between solute and solvent. after saturation, the capacity for the attractive forces is reached and no more solute can be dissolved</span>
Answer:
Actual yield = 20.03g
Explanation:
% 
= 
Actual yield = % yield.(theoretical yield) / 100
Actual yield = 75.26.7/100
Actual yield = 20.025
The atom<span> then has more protons than electrons and so it will be positively charged, a positive </span>ion<span>. Example: A </span>magnesium atom<span> may lose two electrons and </span>become<span> a Mg2+ </span>ion<span>. Non-metal </span>atoms<span> may gain electrons and </span>become<span> negatively charged. ... (It loses two electrons.)</span>
