Explain in terms of electron configuration why selenium and sulfur have similar chemical properties

they have the same chemical properties, because their electronic configuration ends with 6 valence electrons.

Explanation: selenium and sulphur have similar chemical properties because according to their electronic configuration, they both have the same valence electron(6). This valence electron makes them to fall under the same group. Elements in the same group tends to have similarities in their chemical properties.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
