The third shell has 3 subshells: the subshell, which has 1 orbital with 2 electrons, the subshell, which has 3 orbitals with 6 electrons, and the subshell, which has 5 orbitals with 10 electrons, for a total of 9 orbitals and 18 electrons.
I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.
Answer:
Selenium
Explanation:
Oxygen is present in the group sixteen.
This group consist of oxygen, sulfur, selenium, tellurium and polonium.
All of these have same number of valance electrons thus they show similar properties.
From the given list of elements only selenium is belong to oxygen family thus it has properties similar to the oxygen.
Electronic configuration of oxygen:
O = [He] 2s² 2p⁴
Electronic configuration of selenium:
Se = [Ar] 3d¹⁰ 4s² 4p⁴
While aluminium, boron and phosphorus are belongs to other groups that's why their properties are not similar to the phosphorus.
phosphorus is present in group 15.
Boron and aluminium are present in group 13.
The number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.
<h3>
Number of beats of the person</h3>
The number of beats of the person is calculated as follows;
n = bt
where;
- b is the beat rate
- n is number of beats
- t is time or duration
b = 75 beats/min
t = 1.7 years = 893520 mins
n = 75 beats/min x 893520 mins
n = 67,014,000
n = 6.7 x 10⁷ beats
Thus, the number of beats the person have in 1.7 years is 6.7 x 10⁷ beats.
