On a weight basis, carbon is 19th in order of elemental abundance in Earth’s crust, and there are estimated to be 3.5 times as many carbon atoms as silicon atoms in the universe. Only hydrogen, helium, oxygen, neon, and nitrogen are atomically more abundant in the cosmos than carbon. Carbon is the cosmic product of … WebAnswer: Astatine is the element with atomic number 85, which puts it in group/family 17. It is both a non-metal AND a halogen. It’s a nonmetal because of its properties, and a halogen due to its electron configuration (needs one electron for a full valence shell). It is NOT a Noble gas, as they ...

WebJan 3, 2024 · Why is astatine the least reactive halogen? This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. For this reason, fluorine is the most reactive halogen and astatine is the least reactive of the halogens.
