100
Periodic Law states that elements are arranged by _______ and periodically by physical and chemical ______.
atomic number, properties
100
3p3
phosphorus (P)
100
the transition metals are __ and __ blocks.
d and f
200
Which element has the following electron configuration: 1s22s22p63s23p64s1?
Potassium (K)
200
Which atom is bigger: Na or P?
Na
(as go across a period, more protons increases the effective nuclear charge making the atom smaller)
200
What is the Family Name for Group 17?
Halogens
200
the only liquid halogen
bromine (Br)
200
Explain the current atomic model.
the Electron Cloud Model: electrons are in clouds of probability around the nucleus
300
What is the electron configuration for arsenic?
1s22s22p63s23p64s23d104p3
300
Which atom is bigger: fluorine or iodine?
Iodine
(as you go down a group, shielding increases which increases the size of the atom)
300
Elements in the same period have the same number of ______.
Energy levels
300
the only nonmetal in Group 14
carbon (C)
300
Which energy level comes after 4s?
3d
400
What is the noble gas configuration for silver (Ag)?
[Kr]5s24d9
400
Which is smaller: Ca or Ca+2 ?
Ca+2
+2 means that calcium's 2 valence electrons have been lost; one less valence shell makes the radius smaller
400
Based on the Periodic Table, calcium is chemically similar to which of the following?
Mg
K
C
Sc
Mg
400
4d6
ruthenium (Ru)
400
the shape of the electron cloud is indicated by the ____.
sublevel
500
What is the orbital notation for phosphorus?
500
Which has a greater ionization energy: Li or F?
F
ionization energy increases across a period
500
Define first ionization energy.
The energy needed to remove one valence electron from an atom.
500
the only gas in Group 1
hydrogen (H)
500
Which of the following transitions releases energy?
4p --> 5s
3d --> 4p
1s --> 2s
5p --> 4d
5p --> 4d
(this is a higher energy level to a lower energy level which releases energy)
