Given
Atomic symbol
Required
Atomic composition
Solution
Atomic number = number of protons = number of electrons
Mass Number (A) is the sum of protons and neutrons
Number of protons and Number of Neutrons in nucleus
Number of electrons in the shell
From the picture:
protons = 3
neutrons = 4
electrons = 3
atomic number = protons = electrons = 3
mass number = protons + neutrons = 3+4 = 7
The answer is “Heat Conduction”
It is called the scientific method
Answer:
Hover for more information. Phosphine is an example of a polar molecule with non-polar bonds. ... The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution and that's why the molecule is polar even though it has non-polar bonds. Its shape is trigonal pyramidal.
