Answer:
I think #3 might be the answer .
Because in #1 atomic mass tells mass .
#4 Atomic number doesnot only tell about the electrons atom has
Answer:
2 electrons
Explanation:
There are five 3d orbitals, each of which can hold up to 2 electrons, for 10 total electrons. An orbital is described by the principle quantum number, n, the angular momentum quantum number, l, and the magnetic quantum number, ml.
Answer:
Tile 52 and three are incorrect
Explanation:
Answer:
They reduce the bond angle to be slightly lower than the tetrahedral bond angle, approximately 104.45 degrees.
Explanation:
The unshared pair of electrons or lone pair electrons in order to have the minimum repulsion possible with each other pushes the other bonding pairs closer together making the bond angle smaller or bent.
The bond angle is slightly lower than the tetrahedral bond angle of 108 degrees, leaving the water molecule with a bent molecular geometry.
