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.
The four inner planets, those closest to the Sun, are Mercury, Venus, Earth, and Mars. They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases.
Answer:
False
Explanation:
Carbon dioxide is made up of polar molecules, but the dipole moments cancel each other out. Therefore, not a polar molecule.
Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
