to complete the lewis structure, electrons are rearranged to make __ with the central atom as needed to satisfy the octet rule. coordinate ionic bonds multiple bonds hydrogen bonds ionic bonds question 19 1 pts the first step in creating a lewis structure is to add up the __ of all the atoms of the molecule or polyatomic ion. valence electrons ionic bonds protons nuclei

Explanation:

1. In Lewis structures, to satisfy the octet rule for the central atom, electrons are rearranged to form multiple bonds (such as double or triple bonds) when single - bonds do not provide enough electrons. Coordinate ionic bonds are not a common way to complete Lewis structures for the octet - rule satisfaction in the general sense. Hydrogen bonds are intermolecular forces and not used to complete a Lewis structure for an individual molecule. Ionic bonds involve the transfer of electrons between atoms to form ions and are not directly related to rearranging electrons within a molecule to satisfy the octet rule for the central atom.
2. The first step in creating a Lewis structure is to count the valence electrons of all the atoms in the molecule or polyatomic ion. Valence electrons are the ones involved in bonding and determining the structure. Ionic bonds are formed after the Lewis - structure is determined and atoms bond. Protons are in the nucleus and not directly related to the initial step of creating a Lewis structure. Nuclei are the central part of an atom containing protons and neutrons and are not counted in the first step of Lewis - structure creation.

Answer:

Question 18: multiple bonds
Question 19: valence electrons
