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 the 79th element in our periodic table. it has 79 protons in the nucleus plus 79 outer electrons. In the United States and other countries, gold is used to make jewelry.
Why is gold called Au
Gold is element 79 and its symbol is Au. Although the name of the person is Anglo-Saxon, gold comes from the Latin aurum, or brilliant sunrise, and earlier from the Greek. Its frequency in the earth’s crust is 0.004 ppm. 100% natural gold is the Au-197 isotope.
What is a gold atom
Gold is a chemical element with 79 protons in each nuclear atom. Each atom containing 79 protons is a brand new gold atom, and every single gold atom behaves chemically in the same way. So in this method, we can create gold with a simple assembly process of 79 protons (and acceptable for neutrons making the nucleus stable).
What is difference between atomic mass and relative atomic mass
Atomic weight, also called associated atomic mass, is the ratio of the usually average mass of the atoms of a chemical element to a certain standard. … An isotope can be one of two or more types of dinosaur atoms with different numbers of atomic clusters (total protons + total neutrons) of the same current chemical element.
What three things does the atomic mass average atomic mass depend on
An atomic block is the sum of particles of protons, neutrons and electrons in an atom, or the traditional mass in a group of atoms.

What is the difference between relative atomic mass and average atomic mass
And the relative average atomic mass shows two properties of an element associated with its different isotopes. However, Fischer’s relative mass is a standardized number that is considered correct in many cases, while average atomic mass is probably only for an individual sample.
What is the difference between atomic mass and gram atomic mass
When atomic muscle size is defined in grams, it is quickly referred to as grams of atomic muscle mass. When molecular weight is specified in grams, it is more commonly known as gram molecular weight. Declaration of atomic mass at oxygen 16a.m.u. 1 epidermis of oxygen 6 therefore equals at least one Amu = 1.661 × 10^-24 grams.
Why is the atomic mass of an element an average atomic mass
The mass indicated in the periodic table is a fantastic average atomic mass taken from practically known isotopes of the element. This average is a weighted average, which means that it is the relative abundance of the isotope and its effect is changed to the final average. This is because there is no defined mass for an element.
What is difference between atomic mass and gram atomic mass
The atomic mass of a gram of a particular element, as defined, can be the new mass of one mole produced by the atoms of the particular element. It is almost certainly numerically equivalent to the value associated with the element’s atomic mass unit, but in this case has the unit in grams. For example, the mass of a carbon atom is 12? or atomic mass units for twelve months.
What is the difference between molecular mass and molar mass calculate the molecular mass and molar mass for carbon monoxide
Manual The unit of measure for the molecular weight of a solution is kg or R or U. The molar mass is our own molecular weight of the important substance/particle. Molar mass is packaged in g/mol or kg/mol. The molecular speed of CO is 28 u, so the molar mass is 28 g/mol.
