The isotope notation
Solution
Isotopes are elements that have the same atomic number with a different mass number
The following element notation,
X = symbol of element
A = mass number
= number of protons + number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
So the mass number of element = 53 + 20 = 73
Atomic number = 53
The symbol :
Answer: Values of
A =
B =
C =
D = 95pm
E = 1139.9kJ/mol
F = 737.7kJ/mol
G = 495.8kJ/mol
Explanation: We are asked some of the atomic and orbital properties of elements.
Atomic Radii: This is a atomic property of an element which refers to the total distance from the atom's nucleus to the outermost shell. It is usually expressed in .
Ionic Radii: This is also a atomic property of an element which refers to the distance between the nucleus of the two gaseous atoms touching each other. It is usually expressed in pm.
First Ionization Energy: This is an orbital property which refers to the energy required to remove one mole of loosely held electron from one mole of gaseous ions. It is usually expressed in kJ/mol.
