How many electrons can the s orbital hold
Which term describes the describes the disorder of random molecular motion
Does H2 have a molecular dipole moments
No. H2 does not have a permanent dipole moment.
How is the name of the second element in a covalent molecule changed
The ending of the second element is changed to -ide
Why are prefixes not needed in naming ionic compounds
Ions combine in only one ratio, so prefixes are not needed.
How does one determine the number of core electrons an atom has
subtract the group number from the atomic number
Which 2 atoms form a covalent bond
If the electronegativity difference between two atoms is below
1.7, then the two atoms form covalent bond.
What elements have the largest first ionization energy
Which electrons in an atom have the highest energy level
What is the correct electron configuration for an element with 5 electrons in the 3d energy sublevel
When would dipole dipole be significant
Dipole-dipole forces play a significant role when a molecule is
polar.
Which molecule or ion has a trigonal planar shape
how should you indicate that there are multiple polyatomic ions in a chemical formula
put parentheses around the atoms in the ion and then add a subscript - apex
