Which direction do periods go on the periodic table?
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
What is a row in a the periodic table called?
A row of the periodic table is known as a period.Related Information:Across a period, you can see how the electrons fill the energy levels from the s sub-level to the p sub-level. The highest-filled energy levels correspond to the row, or period, number. Down a group, you can see how many valence electrons are present in the atoms of each element.
What is the trend in ionization energy of period 3 elements on the periodic table?
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
What are horizontal rows of elements in the periodic table?
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
Does electronegativity increases or decreases as you move left to right across a period on the periodic table?
Electronegativity generally increases as you move left to right across a period on the periodic table. This is because the effective nuclear charge increases, pulling electrons closer to the nucleus and making it easier for the atom to attract electrons.
The row of elements going left to right on the periodic table is called?
This row of chemical elements is a "period".
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
How does the reactivity of each group of metals change across the table from right to left?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metal of change across the table from left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metals change across the table left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
What is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What is the term for a row of elements going from left to right on the periodic table?
Period
Which characteristics both generally decrease in period three from left to right?
Atomic radii decreases from left to right in the periodic table
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What elements in a period on the periodic table become?
more metallic moving from left to right
How does electronegativity change from left to right in a period within the periodic table?
Going Up
What do you notice about the number of as you move from left to right across the period in the periodic table?
it increases
