Answer is: a single atom of chlorine.
Chlorine has electron configuration: ₁₇Cl 1s²2s²2p⁶3s²3p⁵.
According to his electron configuration, chlorine needs one electron to achive noble gas configuration (most stable because <span>valence shell is filled).
NaCl, H</span>₂O and Ar have stable electron configuration.
Carbon monoxide is the 2 in co
Answer:
five half lives
Explanation:
Half-life is the time required for a quantity to reduce to half of its initial value.
How many half lives it would take to reach 3.13% form 100% of it's initial concentration:
100% - 50% : First Half life
50% - 25%: Second Half life
25% - 12.5%: Third Half life
12.5% - 6.25%: Fourth Half life
6.25% - 3.125%: Fifth Half life
This means it would take five half lives to get to 3.125% (≈ 3.13%) of it's original concentration.
