Me timed test i appreciate your
im struggling

1 an electron is in 4th orbital and it becomes excited. which happens to it?
it would move down to the 3rd orbital
it wouldnt move at all
it would move up an orbital
it would move in between two orbitals

2. the more orbitals an atom has the lower its ionization energy is
true or false

3.during nuclesr change which of the following is false?
energy is conserved
heat is absorbed
heat is produced
the nucleus changes

4. magnesium-29 goes theough alpha decay what isotope does it form?

5.nuclear fission is the process used to power the sun and stars
true or false

number 5 is true but as to the others it's been a while so I don't quite remember...

Explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
