Answer:
2s2 2p5
Rb < Sr< Sn< Te<I
Explanation:
Electron affinity is the ability of an atom to accept electrons to form negative ions.
Electron affinity is a periodic trend that decreases down the group but increases across the period.
This accounts for the trends observed in the answer. The atom having the electronic configuration, 2s2 2p5 must be a halogen and it exhibits the highest value of electron affinity.
Also, since electron affinity increases across the period, the electron affinities of the elements increases. Therefore, the arrangement of atoms as shown in the answer depends on increasing electron affinity.
A scientific theory is a well tested explanation of a natural phenomenon.
<h3>Answer:</h3><h2>NADPH and ATP</h2><h3>Explanation:</h3>
When the light absorbs by the photosynthetic apparatus, the water molecules break down to produce essential material to continue the photosynthetic cycle as electron and H-ions. The H-ions becomes stored in thylakoid chamber and passed through the ATP synthetic machines to refill the ADP or AMP molecules. The generated electron passes through the various stages of photosynthetic series to finally produce the NADPH which also acts as energy transfer compound. At the PSI, the electron transfer to the NADP to generate NADPH.
Answer: D- A seed that contains an embryo plant grows into a young pine tree.
Explanation: The embryo plant comes from a pinecone seed so it can grow into a new plant.
