Write the electron configuration for Br- and state the number of valence electrons. Select one:
Aleks04 [339]

Answer:

1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^62} 4s^{2} 3d^{10} 4p^{5} with 7 valence electrons.

Explanation:

Bromine has 7 unpaired (valence) electrons in its outer shell, and a total of 35 elecrons. Its <em>4s</em> orbital is completely filled with 2 electrons.

The closest answer from the options would be option D.

I hope this helps.

What do you notice is different about the arrangement of the H 2 O molecules in solid form compared to the arrangement of molecu
Nonamiya [84]

Answer:

when the water is frozen, the molecules are tight and bunched together because its a solid. Although that the molecules seem to be tight, it does not meant that the molecules are not moving. The molecules in H 2 O solid form makes them move fast as in vibration. If the H 2 O was in liquid form, the molecules would be spread out and there would be plenty of room to move. But if the H 2 O is a gas, the molecules are even more loose that the liquid and they do whatever they choose to.

Compared to the ideal bond angle, the actual/real bond angle in a molecule of water will be:______.
inna [77]

Answer: d. smaller.

Explanation:

Hybridization :

N=\frac{1}{2}[V+N+A-C]

N = number of electrons

where, V = number of valence electrons present in central atom i.e. oxygen = 6

N = number of monovalent atoms bonded to central atom=32

C = charge of cation = 0

A = charge of anion = 0

The number of electrons is 4 that means the hybridization will be sp^3 and the electronic geometry of the molecule will be tetrahedral.  The bond angle for tetrahedral geometry is 109.5^0

But as there are two atoms around the central oxygen, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent and the bond angle will be smaller than expected and is 104.5^0
