The atom that is most likely to lose an electron is lithium (Li).
<h3>What is electronegativity?</h3>
Electronegativity is the tendency, or a measure of the ability, of an atom or molecule to attract electrons when forming bonds.
On the other hand, electropositivity is the tendency of an atom to release electrons to form a chemical bond.
Chemical elements that lose electrons become positively charged while elements that gain electrons become negatively charged.
Metals are most likely to lose electrons to form positive ions. Examples of metals are lithium in group 1, calcium in group 2, aluminium in group 3 etc.

What is the percent yield if 4.65 g of copper is produced when 1.87 g of aluminum reacts with excess copper (II) sulfate? 2Al (s) + 3CuSO4 (aq) → Al2 (SO4)3 (aq) + 3Cu
I think it is the first choice
Hope that helped!
Answer: G Atom 1 and Atom 4.. hope this helps and good luck!
0.84 milligrams of a 2. 000 mg sample remain after 6. 55 years, according to radioactive decay.
Given data,
amount of sample = 2.000mg initially = 0.002grams
According to radioactive decay,
(
)λ = 
= 
= 0.133
According to radioactive decay,
- λt
= ln0.002 - (0.133×6.55)
= -6.21 - 0.87 = -7.08 = 0.00084g = 0.84mg
Therefore, 0.84 milligrams of a 2. 000 mg sample remain after 6. 55 years.
