An atom of copper has a mass number of 63 and an atomic number of 29. How many protons does it have?
Because it has 29 protons in its nucleus. The atomic number is the number of protons in an elements nucleus.
Why is the atomc mass not a whole number?
The atomic mass listed on the periodic table is a weighted average of all the known isotopes of an element. Since isotopes have different masses based on the number of neutrons they contain, the average atomic mass is not a whole number. It accounts for the abundance of each isotope in nature.
Did anyone believe Democritus proposed that atoms are held together by chemical bonds?
No, Democritus did not propose the concept of chemical bonds. He was known for his atomic theory, which proposed that matter is composed of indivisible particles called atoms that are in constant motion. The idea of chemical bonds to hold atoms together was developed much later in history by scientists such as Gilbert Lewis and Linus Pauling.
Which information is included in each square of the periodic table of element?

What are the rules fr multiplication and divisions of integers?
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons

How do you find the number of neutrons from the mass number?
To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.
Can a real number that is not a rational number is a?
A real number which is not a rational number is an irrational number.
