Gold is a chemical element with the symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. Wikipedia

Why is gold’s atomic number 79
Gold is probably the 79th element in the periodic table. it has 79 protons in the nucleus and 79 outer electrons. In the United States and other countries, gold is used to make jewelry.

How do we find atomic mass
The moving number of protons and the number of neutrons together determine the mass distribution of the element: mass number = protons + neutrons. If you just want to calculate the number of neutrons in an atom, you can often just subtract the number of protons or atomic number from the mass number.
What is difference between atomic mass and relative atomic mass
Atomic weight, also known as relative atomic mass, is the ratio of the atomic mass of the atoms of a good chemical element to the specific mass. … An isotope is one of two or more kinds of atoms with different shared atomic numbers (total protons + total neutron beam) of the same element in solution.
What three things does the atomic mass average atomic mass depend on
Atomic mass is simply the sum of the foci of protons, neutrons, or electrons in an atom, or the ordinary mass in a group of related atoms.
What is the difference between relative atomic mass and average atomic mass
Fischer relative and mean masses describe the properties of a large element in the context of its unique isotopes. However, relative atomic mass is your standardized number and should be correct in most cases, while average atomic mass only applies to a specific sample.
What is the difference between atomic mass and gram atomic mass
When atomic mass is expressed in grams, we often talk about atomic mass in grams. When the molecular weight is defined in grams, it is called the gram molecular weight. The claimed atomic weight of oxygen is 16 amu. 1 mole corresponds approximately to oxygen 6. Therefore, 1 a.m.u. = 1.661×10^-24 grams.
Why is the atomic mass of an element an average atomic mass
The mass derived from the periodic table is any average atomic mass taken from plus or minus all known isotopes of an element. This average is a weighted average, plot the relative abundance of the isotope whose switches affect the final average. The reason is that the element does not have a fixed mass.
What is difference between atomic mass and gram atomic mass
The sum of gram-atoms of an element can be interpreted as the mass of pores and skin of a fraction of a given fraction. Whether it is numerically equivalent to the new value of the conventional atomic unit of the element, but whose unit is grams. For example, the mass of a carbon atom is equal to or 12? twelve units of atomic tissue.
What is the difference between molecular mass and molar mass calculate the molecular mass and molar mass for carbon monoxide
Classical solution The unit of molecular weight is usually cor g or g u. The molar population is the mass of the epidermis of a substance/particle. The unit of molar size is g/mol or kg/mol. The molecular weight of CO is 28u and the molar mass is 30 g/mol.
