it can hold 5 orbitals in the 4d sunshell and there 5 in the orbital i believe that a maxama of ten electrons allowed if im wrong then im sorry
Answer:
The answer to your question is the first choice (H₂)
Explanation:
Process
Look for the electronegativity of the elements of this exercise
a) H₂ = 2.2 - 2.2 = 0
b) NaF = 3.98 - 0.93 = 3.05
c) HBr = 2.96 - 2.2 = 0.76
d) HS⁻ = 2.58 - 2.2 = 0.38
The molecule that has the smallest difference in electronegativity is H₂
The number of electrons, which are present in the nonbonding π molecular orbital of the allyl anion is "0".
Anions, cations, but also allylic radicals have always been frequently mentioned as reaction intermediates. Each one has three adjacent 
-hybridized carbon centers, and they all rely on resonance for stability. Two resonance structures would be used to present each species, with the charge as well as unpaired electron scattered across both the 1,3 and 0 positions.
The Aufbau principle states that these orbitals would fill up based on the order of stability, therefore a typical pi bond, will have 2 electrons in the Pi orbital as well as zero in the Pi* orbital.
Therefore, the correct answer will be option (d)

Answer:
Plasma
Explanation:
It is because gas and plasma have no definite shape and volume but plasma can conduct an electric charge
Carbon -14 and Carbon 12 are the two substances geologists use in radiocarbon dating.
Answer: Option B
<u>Explanation:
</u>
Radiocarbon dating denotes the determination process of the age of fossils of plants or animals based on the ratio of carbon atoms 14 to 12. Carbon naturally exists in two non-radioactive isotopes, Carbon-12 and Carbon-13 and one radioactive isotope carbon 14. The carbon 14 gets released on continuous cosmic reaction with atmospheric nitrogen.
These carbon 14 will be absorbed by the living plants and from the plants. Then, it will enter inside the animals which consume the plants. But once the plants and animals died, they ceased to intake carbon-14. In their living state, the ratios of carbon atoms 14 to 12 in them tends to similar to the ratio in atmosphere.
But after they die, the ratio of C-14 to C-12 will be varying from the ratio of C-14 to C-12 in atmosphere as the concentration of C-14 will be decreasing in the dead animals and plants. Thus using this ratio, geologists can find the fossil's age.
