Answer:
D. Fluorine.
Explanation:
For an atom to accept an electron, from another atom, it must have high electron affinity compared to the other elements.
Large atoms then to have high electron affinity compared to smaller atoms and most large atoms are non metals while elements with smaller atomic radius are metals. Tin(Sn), Arsenic(As) are metals and they have lower electrons affinity compared to Sulfur (S) and Fluorine (F).
Fluorine have a high electron affinity than Sulfur and hence has a larger atomic radius and can easily draw most of the electrons shared between the two atoms.
There's a trend to electron affinity and I.e it increases down the period and decreases down the group.
Most group (VII)A elements form electrovalent compounds due to their tendency to pull the shared electron towards them(high electron affinity) compared to Sulfur (a group VIA) element.
Speed is the speed that object is moving on while velocity is the direction and movement speed you can make it but velocity no
Velocity causes acceleration

Answer:
Biotic factors are the living component of an environment while abiotic factors are the non living component of an environment.
Biotic factors of Mono lake include plants, animals, fungi, algae and bacteria
Abiotic factors of Mono lake include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability.
While the biotic and abiotic factors on Land inhabited by humans including Me are :
Biotic factors-Plants ,animals, bacteria
Abiotic factors-Sunlight, heat/ temperature, Climate, weather, water sources.
Answer: If the woodpecker drums upon a tree 5 times in one second, then the frequency is 5 Hz; each drum must endure for one-fifth a second, so the period is 0.2 s.
