Why do alkali metals and halogens like to "date"? (Hint: Consider the ions formed by elements in each family/talk about electrons in your answer!)
Alkali metals form +1 ions whereas halogens form -1 ions. therefore, the charges between them create an electrostatic force which attract them together

Imagine you have just discovered element 118. Answer ALL the questions. a. From its location on the periodic table, what predictions can you make about its chemical properties/characteristics?
Since the element is 118 will fall under group 18/8A, it will mean the element will be a noble gas, which is extremely nonreactive
Which element in each pair that has a lower ionization energy? O or Te
Te
is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom
Valence Electrons
Compare and contrast atomic radius vs. ionic radius
atomic radius is the distance from the center of the nucleus to the outermost electron atom where as ionic radius is the distance from the center o there outermost electron of the ion
Neon, Argon, and Krypton are:
in the same group
energy required to remove an electron from an atom
ionization energy
What is ionization energy? What are the units? What element has the greatest ionization energy?
is the energy required to remove an electron from a gaseous atom i/mol, Florine will have the greatest ionization energy
Is it easier to remove an electron from an atom with a smaller radius or an atom with a larger radius? Why?
it is easier to remove an electron from a atom with a larger radius than one with a smaller radius because in the larger radius atom the electron is far from the nuclear force or the smaller nucleus is very small compared to the smaller radius
What is the meaning of electronegativity?
the likely hood that an atom will attract a electron move, when moving clockwise on the PT it increases the electronegativity
What is the MOST electronegative element on the periodic table? Which group is it found in?
the most electronegative element on the PT is Florine and is in group 17 or 7a

Some alkali metals are stored in tubes of argon gas. Why would argon be a safe gas to store an alkali metal in?
Because argon is extremely nonreactive so, strong Li will be safe to do so.

Explain why Neon (Ne) has a greater ionization energy than Lithium (Li). (Hint: you should include electrons in your response)
Neon has the greater ionization energy due to the fact that it has a full valence electrons and nonreactive therefore is takes a higher amount of energy if you want to remove an electron in addition neon has a smaller atomic radius which makes it difficult to remove an electron
