There are 6 atoms of hydrogen in the compound H2H4O2.
The number of atoms in a covalent compound depends on the specific compound. Covalent compounds are formed when atoms share electrons, so the number of atoms involved in a covalent compound will be determined by the elements present and the chemical formula of the compound.
There are three calcium (Ca) atoms in the compound Ca(NO3)2.
There are 8 atoms in the compound K3PO4, consisting of 3 potassium (K) atoms, 1 phosphorus (P) atom, and 4 oxygen (O) atoms.
There are 2 nitrogen atoms in one molecule of the compound AlNH3.
compound
Silicon Oxide is not an element; it is a compound.
The number of atoms in one gram of sand can vary depending on its composition, but if we consider typical quartz sand, which is primarily composed of silicon dioxide (SiO₂), it contains about 2.65 grams per cubic centimeter. One gram of quartz sand would contain approximately 0.037 moles of SiO₂. Since each molecule of SiO₂ consists of three atoms (one silicon and two oxygen atoms), one gram of sand contains roughly 6.02 x 10²³ atoms, or about 2.2 x 10²⁴ atoms.
There is no such compound, so it's kind of pointless attempting to name it. Well actually, the chemical name of SiO is Silicon Monoxide. You use the prefix mono- because there is only one oxygen.
