Question

Indicate whether the sentence or statement is A) true or B) false for 1-8.

1 atoms form bonds in such a way as to produce the electron configuration of noble gas.

2 cesium is an example of an element with a high electronegativity.

3 the shielding effect would be greater in an atom of chlorine than in an atom of fluorine.

4 conductivity in metals can be explained by what is called a sea of electrons.

5 all diatomic molecules are linear.

6 the maximum number of electrons in any p sublevel is six.

7 the maximum number of electrons in any f sublevel is 18.

8 in general, the closer an orbital is to the nucleus. the more energy an electron possesses.

9 which of the following orbitals is closes to the nucleus?
A. 1s B. 2p C. 4s D. 3d

10 compare the maximum number of electrons possible in sublevel 3d with the maximum number that could be in sublevel 4d.
A they are the same
B there are more in 3d
C there are more in 4d
D they are impossible to comare

Answer 1

I'm not sure of all of the answers, but the other answer was way off, so I had to answer.

T - Compounds bond to form the lowest possible energy levels. In ionic bonds the electrons are shared unfairly (on purpose). Take NaCl The Na essentially gives up it's extra electron to have filled orbitals that look like Ne and the Cl takes the extra electron to have orbitals that look like Ar. For compounds that are not as electronegative as Cl or with such low ionization energy like Na, they share more evenly and fill both compounds orbitals.
F - Cs has a relatively low ionization energy, not electronegativity.
T - more filled orbitals between protons and valence electrons is the definition of shielding.
F - don't know about this one, never heard the term before.
T - try drawing anything but a straight line between two points
T - six it is
F - believe it's 14 (lanthanides)
F - electrons have the same energy
A - can't get closer than 1s
A - d orbitals can have 10 electrons. Period.

Hope that helped!
Good luck!

Answer 2

I suppose if he has a medical professionals word pronouncing that he was once too sick to do the tests (with dates distinct) then he can enchantment / the institution can enchantment on his behalf, and the mock tests shall be despatched to the examination board to be moderated after which a grade is given. As lengthy as there's a legitimate medical professionals word, and whole mock tests have been despatched (there is a lady in my 12 months present process chemo and she or he is not able to enchantment for a few topics, as we best did part of a few papers) I suppose an enchantment could be triumphant, however I'm no longer certain. I'm from the UK if that makes a change.

Answer 3

false : 1,5,3,8
true: 2,3,4,7,6

9-1s
10- there r more in 3d
