My teacher does not want to teach me. Don't worry I'll post more questions. This is just what I have so far. 1. I'm confused about electron configuration. I'm not sure how I should write the exponents. When I go to the next period in the Periodic Table I'm not sure if the oribitals/exponents should start over and what numbers to start at. It also gets confusing when I get into sifferent blocks. I'm practicing writing the electron configurations but got stuck on Ag because I'm not sure what I should do when I get to the D block.

For Ag so far I have
1s^2 2s^2 2p^2 2p^3 2p^4 2p^5 2p^6 3s^2 3p^1 3p^2 3p^4 3p^5

And then I stopped because I was confused.

Also I'm confused why to skip 3s^1?​

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol

For each of the compounds below, show that the charges on the ions add up to zero. a. kbr b. cao c. li(2)o d. cacl(2) e. alcl(3)

What will most likely happen when two bromine atoms bond together?
