Respuesta:
f. room temperature it's said to be around 25ºC, melting point for iodine is 113.7ºC, so at 25ºC iodine should be solid.
g. iodine is a halogen, which are all of them considered nonmetals.
h. (supongo que puedes mirar la tabla períodica para obtener esta información y que por tanto no necesitas hacer la configuración electrónica para este apartado, si no es así por favor házmelo saber y edito la respuesta) iodine is located in period 5 group 17, elements located in group 17 are called halogens.
i. (realmente no sé a qué nivel necesitas la distribución de los electrones)
nivel avanzado (configuración electrónica): [tex][Kr] 5s^{2} 4d^{10}5p^{5}[/tex], (completa sería: [tex]1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{10} 5p^{5}[/tex])
nivel estándar: 1st energy shell: 2, 2nd: 8, 3rd: 18, 4th: 18, 5th: 7
j. there's only one iodine isotope stable enough to be considered natural, and that's iodine-127 (sería mejor poner 127 arriba en chiquitito antes de la I, pero no sé cómo ponerlo con el editor de ecuaciones de brainly), so its abundance is the 100% of the iodine present on Earth. (there's a second isotope but its abundance is resumed to traces and its half-life is not long enough to be considered a nuclide, so is not significative, that isotope is iodine-129)
k. because iodine is considered a monoisotopic element, its relative atomic mass is the same as its atomic mass, so it can't be calculed, it's 126.90447 u
Espero que te haya ayudado, la verdad que nunca hablé de química en inglés así que me disculpo si hay errores.
