Answer:[Kr]4d^{10}5s^25p^1

Explanation:

The element Indium with atomic number 49 will have 49 protons and 49 electrons in it.

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies and the nearest noble gas is Krypton with 36 electrons.

The electronic configuration in terms of noble gas configuration is:  

In:49:[Kr]4d^{10}5s^25p^1

Boron (B) has two isotopes, boron-10 and boron-11. The atomic weight of boron is ?
suter [353]

Answer:

Approximately 10,5

Explanation:

The question is not really very specific, because it would need the percentages of those isotopes in the nature. As they are not shown, it should be the median of those two numbers.

atomic weight ≈ \frac{10+11}{2} = 10,5

If you check a periodic table, you'll see it's actually 10,8, but that's because of the thing I told you at first (percentages missing).

Hope I could help.
