. A certain diatomic element is a colorless gas and is highly reactive. It has three isotopes with mass #’s 16, 17 and 18 i. What is the naturally occurring diatomic element ? (2 points) ii. Write the isotopic symbols. (2 points) iii. How many neutrons does each possess? (2 points) iv. What is the electronic configuration of each isotope?

i.

ii.

iii. 8, 7 and 9 neutrons respectively

iv. All have same electronic configurations

just did the assignment and the answer was #1 +2 n

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
