300
the group that is the most reactive metals are the ______ while the most reactive nonmetals are the ___
What is the alkali metals and halogens
300

Ionization energy values for lithium includes 7297 and 520. Which is lithium's first ionization energy and which is lithium's second ionization energy?

What is first- 520, second- 7292

300
Electronegativity tends to _____ as you move across a period and ____ as you move down a group.
What is increase and decrease
300
a positive ion is known as a ____ while a negative ion is known as ___.
What is cation and anion
400
explain why ordering the elements by nuclear charge was better than by atomic mass
What is the existence of isotopes that changed atomic mass but wouldn't change atomic number
400
the specific name of the metals in the F block
What is the lanthanides and actinides (inner transition metals)
400
explain why electronegativity values decrease as you move down a group
What is electron shielding- with more energy levels as you move down a group, electrons shield the pull from the protons making it harder to attract electrons.
