The Atomic Number
The element with the symbol At is named astatine.
The mass number of copper (Cu) is 63.5. This can be found by looking at the number located below the symbol "Cu" on the periodic table.
No, snow is not on the periodic table. The periodic table is a chart that organizes elements based on their atomic number, chemical properties, and electron configurations. Snow is a form of precipitation that consists of ice crystals.
Botulinum can be made by men or by a certain kind of bacteria. The remainder of this question, however, signals a serious misunderstanding of chemistry: Everything tangiblemade by man or any other life form consists of one or moreelements on the periodic chart. Botulinum is a compound, containing more than one element. It therefore can not be made from an* element but can be made from a small selection of elements.___________________________________*Note that "an" is an article that can not correctly modify a plural subject.
Mercury is a "pure substance" in the sense that is an naturally occuring element on the Periodic Table. However, it can combine with some other elements in nature and so may not be found in its pure form. cinnabar (HgS) is a common form. That's 1 Mercury atom + 1 Sulfur atom.
True. Row number on the periodic chart will be the same as the shell number.
The element AU on the periodic chart stands for gold.
Arsenic
The chart is called the periodic table of elements, and elements are organized by their atomic number, which corresponds to the number of protons in the nucleus.
by subtracting the atomic number from the mass number. the atomic number is the one under the element's symbol and the mass number is the one above the element's symbol.
Manganese.
chlorine
True. Row number on the periodic chart will be the same as the shell number.
The element Mg is in the 3rd period of the periodic table.
The atomic number of an element is how many protons is in it. So the chart is arranged lowest atomic number to highest.
Mg is the chemical symbol for the element magnesium on the periodic table
Yes. Element #23 on the periodic chart.
