hey
Yes, atoms beyond the second period in the periodic table can have an expanded octet, allowing them to hold more than eight electrons in their outer shell.
The expanded structural formula for an alkane with three carbon atoms is CH3-CH2-CH3, also known as propane. Each carbon atom is bonded to the appropriate number of hydrogen atoms.
Certainly! An expanded structural formula shows all atoms and bonds in a molecule. It provides a detailed visual representation of how atoms are connected within a compound. This type of formula is useful for understanding the arrangement of atoms in a molecule.
he thought everything was made of atoms
Democritus
Democritus believed that all matter was made up of tiny, indivisible particles called atoms that are constantly moving in empty space. He believed that different properties of matter arise from the different shapes and arrangements of these atoms.
Yes, SeO2F2 and ONF3 contain atoms with expanded octets. In SeO2F2, the selenium atom has 12 electrons around it, exceeding the octet. In ONF3, the nitrogen atom has 10 electrons around it, also exceeding the octet. However, GaCl3 does not have any atoms with expanded octets as gallium follows the octet rule.
the Greeks. Atoms were thought to be the last indivisible units, but we've learnt how to split atoms.
democritus
Yes.
Erwin thought it was a wave, and Einstein thought it was a molecule
They really didn't they thought of a theory of everything being made up of atoms. Such as Mendeleev and Mosley
