What is NONMETALS
An alkali metal in the 3rd energy level.
What is sodium?
This element has the following electron configuration:
1s22s22p63s1
What is Sodium?
This is the distance from the nucleus to the edge of an atom.
What is atomic radius?
Who is known as the father of the periodic table?
What is Mendeleev?
Elements located on the "stairstep"
What is METALLOIDS?
This group has 5 electrons in the p block.
What is Halogens?
This element has the following electron configuration:
1s22s22p63s23p4
What is Sulfur?
What happens to the atomic radius as you go across a period and why?
The radius decreases because there are more charges in the nucleus to attract electrons.
This classifies a group as one of the eight representative groups.
What is number of valence electrons?
The transition metals are located here.
What is Groups 3-12?
Ar is found in this group.
What is Noble Gases?
This element has the following electron configuration:
1s22s22p63s23p64s23d104p65s24d105p5
What is Iodine?
What happens to the ionization energy as you go down a group?
It decreases because because the atom gets bigger as you go down a group, so the attraction between the nucleus and electron is not as strong.
Which of these elements has the highest Atomic Radius?
Calcium, Chromium, or Barium
What is Barium?
This group has 8 valence electrons
What are halogens?
The following is a characteristic of Alkali metals.
What is very reactive?
What is 1 valence electron?
What is soft or shiny?
What is ions with a +1 charge?
The following element has an electron configuration of:
[Xe] 6s24f145d7
What is Iridium?
This happens to the electronegativity as you go across a period?
What is electronegativity increases?
What is increasing atomic number?
Elements 58-71 are known as this term.
What is Lanthanides?
What group will create ions with a +2 charge?
[Rn] 7s2
What is Radium?
Describe the difference between electronegativity and ionization energy.
Ionization energy is the amount of energy it takes to lose an electron while electronegativity is the ability to attract an electron to an atom.
The element that has the highest ionization energy.
(excluding: Noble Gases)
