The electronic configuration of an element is given below.
Amiraneli [1.4K]

 The statement  which  is true  about  the reactivity  of  element  with          1S²2S²2P⁶3S¹   is

 it is reactive   because it has to lose one  electron  to have  a full  outermost  energy  level.

<u><em>Explanation</em></u>

  • <u><em> </em></u>Element  with     1S²2S²2P⁶3S¹  electron configuration  is    a sodium  metal.
  •    sodium  has  one  electron  in the outermost energy level.
  • for  sodium to have  a full  outermost  energy level (  8 electrons) it   loses  the  1  electron   in 3S¹ to  form   a positively  charged ion. (Na⁺)

Please Help!
Whitepunk [10]

We can use two equations for this problem.<span>

t1/2 = ln 2 / λ = 0.693 / λ
Where t1/2 is the half-life of the element and λ is decay constant.

20 days = 0.693 / λ 
λ   = 0.693 / 20 days        (1) 

Nt = Nο eΛ(-λt)                (2)

Where Nt is atoms at t time, No is the initial amount of substance, λ is decay constant and t is the time taken.
t = 40 days</span>

<span>No = 200 g

From (1) and (2),
Nt =  200 g eΛ(-(0.693 / 20 days) 40 days)
<span>Nt = 50.01 g</span></span><span>

</span>Hence, 50.01 grams of isotope will remain after 40 days.
