Brass isn't an element: it doesn't have an atomic number. It's an alloy made from Copper (Cu) and Zinc (Zn), atomic numbers 29 and 30, respectively.
Sources: Common household Periodic Table.
Brass as it is an alloy where as all the other three are basic elements. So brass will not be available in the periodic table. No atomic number for brass. But mercury has 80, gold has 79 and Nitrogen has 7 as atomic number.
Brass does not have an atomic weight as it is an alloy. An alloy consisting of Copper (Atomic Weight: 63.546) & Zinc (Atomic Weight:65.38). This is why there is no Atomic Weight available for it. Once in a while a comparison of metals requires commonality. Such as if you were comparing the mass of a Brass item to say one of Lead (Atomic Weight:207.2). Mixtures of Brass vary from 5% Zinc to 45%. As you can easily see the weight of both Copper and Zinc are close in weight, and both are about 1/3 of the Lead. This would mean that if you were making a weight for say "skin diving" if you used lead instead of Brass the lead would be 1/3 the size and identical weight.I hope this had helped you.
the answer is that it is called a atomic number.
The atomic number for hydrogen is 1 and the atomic number for carbon is 6.
No. Sulfur has an atomic number of 16 and Argon has an atomic number of 18

Digest (dissolve) a small portion of the brass in nitric acid. Then test the sample for copper content using an atomic emission or atomic absorption spectrometer.
this elemnt has an atomic number that is double the atomic number of silicon?
the answer is that it is called a atomic number.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
The atomic number is equal to the number of the protons in the atomic nucleus.
Brass is not a compound, because its atomic composition can vary from one sample to another. Instead brass is a mixture, of the special type called an alloy, because it is a mixture primarily of metals.
Subtract the atomic number from the atomic weight.
