PLEASE HELP I DONT HAVE THE TIME TO DO THIS ITS FAIRLY EASY AND DONT ANSWER IF YOU DONT KNOW ITS RUDE
give the electron configuration of vanadium (V), atomic number 23
Give the noble gas configuration of vanadium (V), atomic number 23
List the energy levels for the orbital configuration of vanadium (V), atomic number 23
How does the atomic radius change going down and across the periodic table?
How does the first ionization energy change going down and across the periodic table?
How does electronegativity change going down and across the periodic table?
How does the radius of a positive and negative ion compared to a neutral atom?
Match: A. Ionic bond B. Covalent bond C. Metallic bond __sharing of electrons __freely moving electrons __transfer electrons
Describe the dipole dipole force
Describe hydrogen bonding
Describe the Van der waals forces
Imagine you need to take a medicine that the doctor has prescribed for you. Explain why scientist who developed that medicine would need to know whether or not the compound in that medicine is polar. How might a polar medicine behave differently within your body than a non-polar medicine word? (Answer in 1 to 2 paragraphs)
According to table 2, which is the strongest bond? Which is the week is fine? Based on what you know about the atomic radii and electronegativity of the elements involved in the bonds, why do you think these to have the most extreme bond-energy values?
How are the bond energies of each bond listed in table two determined?
Why do you think there aren’t bond energy values given in table 2 for N-S and S-I?
Based on tables one and two how would you describe the trend in bond strength of single double and triple bonds?
Based on table 2, how would you describe the trend in strength of bonds formed by the elements carbon nitrogen and oxygen? Would you describe this trend as a periodic trend? Why or why not?
What is the VSEPR theory?
How does electron repulsion determine molecular shape?
How do lone electron pairs affect molecular shape?
Draw the Lewis structure for the Se and 2 H atoms
Draw the Lewis structure for the SeH(2) molecule
What shape would SeH(2) have? Draw the molecule

This has nothing to do with school. i wrote a poem to my crush, who i'm asking out soon. tell me if it's cheesy, or cute.
