Atoms- Periodic table

QuestionAnswer
A X Z A- mass # (proton+neutron) Z= atomic number
________ electrons are more influenced by other atoms than its nucleus valence
Neutral atom has equal protons and electrons
________ is always constant even in ions proton number
whats isotope same proton # but different mass #
maximum number of electrons in energy level n 2n^2
how many sublevels (L) in an energy shell 0 to n-1
max electrons in sublevel 4L+2
4s has _____ energy than 3d lower
ml magnetic quantum energy L to -L
two electrons in the different orbital have opposite ________ spins parellel
two electrons in same orbitals have ______ spins paired
eqn to solve which subshell will be filled first n+L (3d= 3+2 4s= 4+0)
what are the valence electrons for IIIA to VIIIA s and p
transition elements have partially filled d sublevels
lanthanide and actinide seriess have partially filled f sublevels
largest atomic radii is located at the bottom of Grp 1
atomic radii ________ across a period decreases
ionization energy amt of energy to remove an electron
ionization energy increases 1. across a period, up a grp 2. second ionization
electronegativity increases across a period and up a grp
________ aka semimetals display characteristics of both metal and non metals metalloids
_______ high mp+bp, can lose various electron from s+d transition elements
valence electrons for grp I n II s
figuring the secon ionization ebergy those with + will have the highest second ionization energy to determine the highest we look at their isoelectronic form in the noble gas section the one higher up will have a higher 2nd ionization
transition elements lose electrons in s before the d

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
