200
Responsible for organizing the periodic table according to increasing atomic mass, credited as the father of the periodic table.
Who is Mendeleev?
200
The trend of atomic radii going down a group of the periodic table and the reasoning behind it.
What is atomic radii increases due electrons being added to higher energy levels farther away from the nucleus?
200
The trend in ionic radius going across the periodic table from left to right for groups 1A-3A & groups 5A-7A as well as the reasoning behind the trend.
What is decreasing from 1A to 3A and decreasing from 5A to 7A & 1A-3A form cations that lose an increasing number of electrons & groups 5A-7A form anions that gain a decreasing number of electrons?
200
The general trend of electronegativity on the periodic table moving across a period from left to right and the reasoning behind the trend.
What is electronegativity increases from left to right until the noble gasses because elements have an increasingly closer number of electrons to an octet which causes them to be more attracted to electrons as it requires less energy to gain them than to lose electrons?
200
The trend in first ionization energy from left to right across a period on the periodic table and the reasoning behind the trend.
What is ionization energy increases from left to right across a period because as an energy level is filled with more electrons it requires more energy to remove an electron because the element is increasingly closer to a stable shell conformation?
300
He organized the periodic table the same way it is organized today, by atomic number.
Who is Moseley?
300
The trend in atomic radii going across a period from left to right on the periodic table and the reasoning behind it.
What is the atomic radii decreases due to increased nuclear charge while electrons are being added to the same energy level or the same distance from the nucleus?
300
The general trend going down a family for ionic radii and the reasoning behind the trend.
What is ionic radii will increase because the previous size of the atom was already larger and the number of electrons are being lost or gained in each family?
300
The general trend of electronegativity on the periodic table moving down a family from top to bottom and the reasoning behind the trend.
What is electronegativity decreases because electrons get added to higher energy levels and are more distant from the positively charged nucleus which is also shielded from attracting the outermost electrons?
300
The trend in first ionization energy from top to bottom going down a family on the periodic table and the reasoning behind the trend.
What is ionization energy decreases because electrons are being added to energy levels that are farther away from the positively charged nucleus and the electrons are shielded from the Coulombic attraction, allowing them to be removed with less energy?
