It’s c because a wave cycle is repeating patterns all over again and again
Answer : The structure of
will be square-planar.
Explanation :
In the given molecule
, 'Xe' is the central atom and 'H' is the terminal atom.
Xenon has 8 valence electrons and hydrogen has 1 valence electron. Therefore, the total number of valence electrons are 8 + 4(1) = 12 electrons.
The number of electrons used in Xe-H bonding = 8 electrons
The remaining electrons which are used as lone pair on central atom (Xe) = 12 - 8 = 4 electrons
There are 4 bonding pairs and 2 lone pairs of electrons, they will be arranged in the octahedral arrangement around the central atom with 2 lone pairs of electrons on central atom. The lone pairs are arranged linearly across the central atom. The resulting structure will be square-planar.
The structure of
is shown below.
PbCr04 + P4O10
Hope this helps!
Electrostatic, meaning the attraction from one's positive nucleus is to the negative electrons of the other atom and vis versa.
