Answer:

Chlorine(Cl)

Explanation:

Because the shielding effect(by the inner electrons) remains the same but the nuclear charge is increasing(due to the increasing number of protons)

So Chlorine has the highest number of protons...so its outter electrons tend to expierence the most nuclear attraction hence making it more harder to remove the first electron

Pleaseeeeeee hlepThe half-life of cobalt-60 is 5.26 years. After 10.52 years, 5 grams of a 20-gram sample will remain.

vladimir1956 [14]

The half-life of cobalt-60 is 5.26 years. After 10.52 years, 5 grams of a 20-gram sample will remain is TRUE

Explanation:

Mass of cobalt = 20 g

Half-life = 5.26 years

Mass remains after 10.52 years = 5 g

This can be solved by using given below formula, $m(t)=m_{o}\left(\frac{1}{2}\right)^{\frac{l}{5.26}}$

$m_{0}$ = initial mass

t = number of years from when the mass was m_0

m(t) = remaining mass after t years

Number of half-lives = $\frac{\text { Time elapsed }}{\text { Half -life }}$

Number of half-lives = $\frac{10.52 \text { years }}{5.26 \text { years }}$

Number of half-lives = 2

At time zero = 20 g

At first half-life = $\frac{20\ g}{2}$ = 10 g

At second half life = $\frac{10\g}{2}$ = 5 g

The given statement is true.

WHY did the changes to the atomic model happen

Tom [10]

The model of the atom has dramatically changed over many many years.We learn atoms make up different substances and are the smallest particles of matter. which can have subatomic particles that are very small portions of matter.at first scientist only thought there were electrons which are negatively charged.
