Anything with "oxide" in the name is not an element, just a compound that contains oxygen. Only elements have atomic numbers, and that of oxygen is 8.
8
The atomic number of Oxygen is 8.
The atomic number of mercury (Hg) is 80. The atomic weight of Hg is 200.59 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
yes you can because the number of protons and electrons is the same in each. they also have the same atomic mass and number.
this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
Zinc oxide is a compound so it doesn't have an atomic number.
The atomic number of Oxygen is 8.
it is 7
oxide is an anion of atomic oxygen.
The atomic number of mercury (Hg) is 80. The atomic weight of Hg is 200.59 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
Deuterium, an isotope of hydrogen, has an atomic mass of 2 since it has a neutron as well as a proton in the nucleas. Hydrogen oxide, H20 is known as water - deuterium oxide is known as heavy water.
The easiest way to solve these problems is to use what is called a unit multiplier. First begin with the number of grams of copper that you have, then use the unit multiplier that expresses the number of grams per mole of copper (this is the number that corresponds to the atomic mass on the periodic table times grams, divided by moles). Then use the number of copper atoms that it takes to create copper oxide; this will depend on the oxidation state of the copper. Finally it reverse the process by adding up the atomic masses of copper oxide, and that will be the number of grams per mole of copper oxide, returning you from Moles back to Grams.
The atomic number of magnesium is 12 and the mass number is 24.305 use the Periodic Table it gives you all the info you need :D
A shiny metallic element with the chemical symbol Fe. It has the atomic number 26 and the relative atomic mass 56. It can form an orangey-brown oxide commonly called rust
all of them
Atomic mass of iron is 56u. Atomic mass of oxygen is 16u. molecular mass of Iron(III) Oxide is 2x56+3x16=160u.
It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.
