PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.
Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.
Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>
It reduces the chance of an extinction given a natural disaster. If there is more diversity and lets say a wildfire happens, more species would survive the event to repopulate the area
The number of values greater than or equal to 8 is mathematically given as
x = 27
This is further explained below.
<h3>What is a data set?</h3>
Generally, Simply put, data sets are groups of information. When dealing with tabular information, a data set is analogous to one or more database tables, where each column represents a different variable and each row represents a separate record.
In conclusion, the total amount of numbers that are either more than or equal to 8
Data value 8 is only exceeded by 9, 10, 11, and 12.
- 8 occurs 4 times
- 9 occurs 6 times
- 10 occurs 8 times
- 11 occurs 4 times
- 12 occurs 5 times
Hence
x= 4+6+8+4+5
x = 27

Explanation:
It is given that,
Initial orbit of electrons, 
Final orbit of electrons, 
We need to find energy, wavelength and frequency of the wave.
When atom make transition from one orbit to another, the energy of wave is given by :
Putting all the values we get :
We know that : 
So,
Energy of wave in terms of frequency is given by :
Also, 
is wavelength
So,
Hence, this is the required solution.
Mechanical and gravitational potential energy
