How Many Valence electrons does the element Radium Have?
2
Which has more ionization energy I or Cl?
Cl as you go to the right and up ionization energy increases
'Frequency and Wavelength have a direct relationship' is this statement True or False?
False
(Reason: wavelength is the distance from one wave to the next. As you have more frequency the distance between waves decrease meaning they have an indirect relationship.)

Te- 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p4
Y - 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d1
'Cations are usually nonmetal and anions are usually metal?'
Is this statement True or false?
False, Cations are usually metal and anions are usually nonmetal.
What is the main element in dishsoap
Sodium LAURYL SULFATE
Which has the the highest frequency?
Infared or Xrays?
x-rays
What do we use to identify elements on the periodic table?
Protons or Atomic mass
How Many Valence electrons does the element Flourine have?
9
Which has a bigger atomic radius Ra or Ba?
Ra because as you go down and to the left on the periodic table atomic mass increase
Which of the following has a greater frequency
microwaves waves or ultraviolet waves?
Ultraviolet waves
What is the max number of valence electrons elements can have?
8
Which element is on period 3 row 14?
'Energy and frequency have an indirect relationship' is this statement True or False?
False!
(Reason : as energy increases so does frequency
making them have a direct relationship)
True or false, The element Gallium has 7 valence electrons
False!
How many valence electrons does Polonium Have?
6
Which of the following has more energy blue or purple
light?
Purple light!
