Consider the following metals A, B c d at room temperature. 10.00 g of each metal absorbs 15 kj which metal will reach highest temperature?

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
