Question

More random chem questions. Most will be on quantum theory/numbering while some are on chemical bonding.
MOST of these are just checking answers. You can ask me for any ideas I've had regarding the questions.

(First one is compound NOT element, oops)

Answer 1

What are the electron pair shape and molecular shape, respectively, of this element?\[\LARGE{\color{darkseagreen}{NO_{3}^{-}}}\]

Answer 2

Which of the following contains an atom that does \(\color{indianred}{not}\) obey the octet rule?

(Just explain to me what "not obey the octet rule" means exactly...)

a, \(SnO_{2}\)
b, CsI
c, ClF
d, \(ClF_{5}\)

Answer 3

What is the Lewis structure for \(\color{steelblue}{Ca^{2+}}\)?

Answer 4

MORE TO COME! You can respond to previous Qs --

Answer 5

When an atom does not obey the octet rule it means that the atom is satisfied with either having more or less than 8 valence electrons. For example BF3 is satisfied with just 6 valence electrons surrounding the Boron atom.

Answer 6

Ca^2+ would have no dots in its lewis structure as its valence electrons have been removed. When creating lewis dot structure for ions you must also include brackets. For example Na^+ would look like this sorry for the bad drawing :P

Answer 7

what do you think for 1st part ?

Answer 8

eh... trigonal planar for electron?

Answer 9

GOOOOD

Answer 10

YAI! ☺

Answer 11

Q: how do I know when is trigonal pyramidal?

also I think molecular shape is ... also trigonal planar?

Answer 12

you are correct

Answer 13

YAI ☼

Answer 14

how do I know when is trigonal pyramidal?
for this, i had already answered it -.-

Answer 15

eheh ^-^;
