Me on these 4 !
1.some atoms are exceptions to the octet rule by having an expanded octet. which characteristic is needed for an atom to have an expanded octet?
the atom has empty d-orbitals.
the atom has more than eight valence electrons before bonding.
the atom has empty p-orbitals.
the atom has fewer than eight valence electrons after bonding.
2. which statement describes the valence electrons in ionic bonds?
they are shared equally between two atoms.
they are shared unequally between two atoms.
they are shared among many atoms.
they are transferred from one atom to another.
3. which of the following metal atoms would have the highest conductivity?
the atom with the smallest radius and the fewest valence electrons
the atom with the smallest radius and the most valence electrons
the atom with the largest radius and the fewest valence electrons
the atom with the largest radius and the most valence electrons
4. how is electronegativity related to covalent bonding?
atoms must have similar electronegativities in order to share electrons in a covalent bond.
atoms must have very different electronegativities in order to transfer electrons in a covalent bond.
atoms must have similar electronegativities in order to transfer electrons in a covalent bond.
atoms must have very different electronegativities in order to share electrons in a covalent bond.
