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
B) just learn that you move the decimal right as numbers go higher and left if numbers decrease
So 1.75 km =1750000
Move decimal to the left to get a scientific notation
So 1.75 x 10^6
