Count the number of electrons, they must equal 8, if not the you must increase the amount of elements to make the numbers work to equal 8. Ions like NO3- has a charge of -1 so it needs one electron to serve the octet rule so an ion like H+ will work because it is +1.
It makes two covalent bonds which completes its octet.
No, it is possible to satisfy the octet rule for XeF2. Xenon has eight electrons in its outer shell (octet) by sharing two electrons with each of the two fluorine atoms in the molecule, resulting in a stable electron configuration.
Fluorine needs one additional electron to satisfy the octet rule, giving it a total of 8 valence electrons and achieving a stable electron configuration.
Molecular formulae that must contain a double bond in order to satisfy the octet rule are those of compounds like O2, HCN, and CO2.
An example of a molecule that follows the octet rule is methane (CH4). In methane, carbon forms four covalent bonds with hydrogen, allowing each atom to achieve a full outer shell of electrons (octet) and satisfy the octet rule.
Each sodium atom will lose one electron to achieve a complete octet in its outer shell, as the octet rule dictates atoms will gain or lose electrons to achieve a stable electron configuration with 8 electrons in the outer shell.
Ionic Bonds are when electrons are exchanged to satisfy the octet of each element reacting. Covalent Bonds are when two atoms SHARE their electrons to satisfy the octet rule.
The 2 outermost orbitals that must be filled to satisfy the octet rule are the s and p orbitals. These orbitals can hold a maximum of 8 electrons in total, which is needed to achieve a stable, full octet configuration for many elements.
Yes, it does.
There are three resonance structures for the nitrate ion that satisfy the octet rule. In each of these structures, each oxygen atom has a full octet by sharing electrons through double bonds with the nitrogen atom.
Strontium typically loses 2 electrons to satisfy the octet rule. Since strontium is in group 2 of the periodic table, it has 2 valence electrons. By losing these two electrons, it attains a stable electron configuration similar to a noble gas.
