These are closer to the nucleus, which results in Cl having a higher electronegativity value than I.
What are electrons?
This trend decreases from left to right across a period due to increasing number of valence electrons being pulled closer to the nucleus of an atom.
What is Atomic Radius?
These are the metals in group 1 of the Periodic Table that are the most reactive group of metals.
What is Alkali Metals?
As you move down a group, the ionization energy electrons are further away from the nucleus, which means less energy is required to take the electrons.
What is decreasing?
These are the non-metals in group 17 of the Periodic Table that are most reactive group of nonmetals.
What is Halogens?
This is what a element's period determines.
What is the number of orbitals?
A greater amount of this causes electrons to be held "tighter" in an atom as you move from left to right across a period for electronegativity.
What is a positively charged nucleus?
This metal has similar properties to Zinc and its atomic mass is less than or equal to 112.
What is Cadmium(Cd)?
This is the rows in a Periodic Table that separate elements based on their number of orbitals.
What is a period?
These are the metals in group 2 of the Periodic Table and are most likely to react with group 16 of the Periodic Table.
What are Alkaline Earth Metals?
These two trends are similar for when higher energy is needed to take an electron from an atom, it signifies how well the atom's nucleus attracts its electrons.
What are electronegativity and ionization energy?
