What factors contribute to the decrease in atomic radius as you move across a period on the periodic table?
The decrease in atomic radius as you move across a period on the Periodic Table is primarily due to increasing nuclear charge and the attraction between the positively charged nucleus and the negatively charged electrons. This stronger attraction pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.

Is the pattern in ionization energy always true or generally true?
The pattern in ionization energy is generally true, but there can be exceptions due to factors such as electron-electron repulsions or orbital hybridization. In most cases, ionization energy tends to increase across a period and decrease down a group on the periodic table.
A row of elements across the periodic table is an?
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
What is is the trend across a period?
The trend across a period refers to how a property of elements changes as you move from left to right across a row in the periodic table. For example, in terms of atomic size, the trend across a period is generally a decrease due to the increasing number of protons in the nucleus pulling the electrons closer.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
The atomic radius decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
When you move across the periodic table from left to right what happens to the number of protons contained by each element?
the numbers increase (going right) and decrease (going left)
As you move across the periodic table what changes in metalic character?
The metallic character decrease from left to right.
Why does atomic size tend to decrease with increasing atomic number across a row of the periodic table?
electronegativity
When you go across the periodic table how does the atomic size go?
Atomic size tends to decrease as you move from left to right across a period on the periodic table. This is due to increasing effective nuclear charge, which attracts the electrons more strongly and pulls them closer to the nucleus.
What do you notice about the boiling points as you move from left to right across the periodic table?
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
Is the pattern in ionization energy always true or generally true?
The pattern in ionization energy is generally true, but there can be exceptions due to factors such as electron-electron repulsions or orbital hybridization. In most cases, ionization energy tends to increase across a period and decrease down a group on the periodic table.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
Is it true Moving across a row of the periodic table the atoms tend to get bigger?
Yes, as you move across a row (period) of the periodic table from left to right, the atomic radius tends to decrease. This is due to the increasing effective nuclear charge, which pulls the electrons closer to the nucleus, making the atoms smaller.
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
What are the 1 2qv factors that contribute to the success of a marketing campaign?
The key factors that contribute to the success of a marketing campaign are effective targeting of the right audience, compelling messaging that resonates with the audience, and strategic distribution across relevant channels.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
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.
