I need some help please, I keep getting ir wrong.1Complete the electronic configuration of the following:Fluorine (Atomic Number: 9): 1s2 2s2 _Potassium (Atomic Number: 19): 1s2 2s2 2p6 2Which of the following elements have an equal number of valence electrons?Na (Atomic Number: 11)O (Atomic Number: 8)K (Atomic Number: 19)3Write the number of valence electrons and valency of aluminium (Atomic Number: 13).4The electronic configuration of the atoms of three elements X, Y, and Z is given belowWhich of these elements are metals?a: 1s2 2s1b: 1s2 2s2 2p5c: 1s2 2s2 2p6 3s2
You and me bothI erected a metal clothesline contraption that someone gave me a million years ago, and I've been hanging stuff to dry for 2 daysTHEN, yesterday, my washer quit spinning water out of the clothes for good, so I wrestled a second older washer into the laundry room and I use it for it's spin cycle aloneThe first washer uses far less water, so I have to keep it, the husband saysAlrightNow my life is revolving around nothing but laundry 24/7We have 5 children, so this is a lot of work for meBut oh wellAt least it's summer.
The dryer belt may need to be replacedI changed a belt once, but you may need to call a repairman to check out the problemDouble check the breakers again before you make the call.
F 1s2, 2s2 2p5 K 1s2, 2s2 2p6, 3s2 3p6, 4s1 Na and K have the same number of valence electrons, 1They are both found in group 1The valency of aluminum is 3It has 3 valence electrons a: 1s2 2s1 lithium (metal) b: 1s2 2s2 2p5 fluorine (nonmetal) c: 1s2 2s2 2p6 3s2 magnesium (metal)
