Please give me the varying trait (what changes) we have discussed as you travel down a group.
The number of energy levels increases by one (1).
100
Who developed the first periodic table and what was it arranged by? (Must get both parts)
Dmitri Mendeleev and atomic mass
100
Light can behave as both a ___________ and a ______________.
particle and wave
100
Type of bond created between two elements to the right of the stair-step line (non-metal and non-metal)
Covalent
200
What does an electron configuration show you?
The number and orbital location of the atom's electrons
200
What is electronegativity?
The ability of an atom to attract an electron. (It wants an electron)
200
Groups 3-12 represent the: s-block, p-block, d-block, f-block
d-block
200
What is wavelength and frequency and how are they related?
Wavelength = length from crest to crest
Frequency = how many times a wave passes a certain point in a defined period of time
As one gets larger, the other gets smaller
200
What types of elements form an ionic bond? (i.e. metals, non-metals, metalloids)
a metal and non-metal
300
Which element has the outer electron configuration of 2s22p2?
Carbon (C)
300
What ion has the smaller atomic radius?
Li or Be
Be; they are in the same period so it depends on which has more protons pulling on the electrons.
300
Which element is represented by the following electron configuration?
1s22s22p63s23p2
Silicon (Si)
300
What is required to get an electron to jump from its ground state (low energy) to its excited state (high energy)?
Absorption of a photon of energy.
300
Draw the Lewis structure for NaOH
See board.
400
Draw the electron configuration for Sodium (Na)
See board
400
Which is more electron negative; N or Br?
N; it doesn't have more energy levels shielding the electrons
400
How many levels is the electron cloud divided into?
Seven (7)
400
A particle property of light that causes metals to appear shiny is the _______________.
Photoelectric effect
400
How can you determine the number of valence electrons an atom has just by looking at the periodic table?
Look at which group it is in
500
Which period 5 element has the same outer electron configuration as Chromium (Cr)?
Molybdenum
500
"The physical and chemical properties of an element repeat in a pattern based on atomic number" is the definition of; periodic, periodic law, electron configuration
Periodic law
500
Who created the modern version of the periodic table?
Glenn Seaborg
500
The emission of light is fundamentally related to the behavior of _______________.
electrons
500
Draw the Lewis structure for KNe
Can't, noble gases already have 8 valence electrons!
