An example is just when they have a a group o numbers, for any reason, and they want to find the average of then all
an example being um idk...numbers resulting from an experiment trying to find different densitys or something and they wanted to find the average density
This is called the Mass Number of the isotope of the atom.
Isotopes are different forms of the same atom. They have the same number of protons but different number of neutrons.
Carbon-12 has mass number 12 as it has 6 protons and 6 neutrons.
Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.
Answer:
atomic number 8 and atomic number 12
Explanation:
atomic number 8 and atomic number 12 , element with the atomic number 8 is oxygen, and the element with atomic number 12 is Magnesium
Magnesium has low ionization energy, hence higher tendency to loose its two outermost electrons to form positive ion.
Oxygen has high electron affinity, hence higher tendency to accept or gain electrons to form negative ion.
The electronegativity difference between the element with atomic number 8 and element with atomic number 12 is greater for the formation of ionic bond
The answer is A, empirical formula is CH2O and molecular is C6H12O6
