You question is not very clearly stated but I think I know what you are asking. As you go down the column of any family of elements in the Periodic Table, you move to increasingly heavier and larger atoms. Their outer electrons are therefore farther from the nucleus, and even though the nucleus is larger and has a larger positive charge, the increased distance is the predominant influence, making the outermost electrons less tightly bound, and therefore more easily ionized, with a lower ionization energy.
What else can I help you with?
When energy is removed what does the decrease in energy causes the particles in that state to do?
When energy is removed, the decrease in energy causes the particles to slow down or cool down. This can lead to a decrease in movement and a potential change in state, such as from gas to liquid or solid.
How can you decrease kinetic and Energy an object has?
To decrease the kinetic energy of an object, you can decrease its velocity by slowing it down. To decrease the potential energy of an object, you can lower its height or remove any external forces acting on it.
What best defines the ionization energy of an element?
The ionization energy of an element is the energy required to remove an electron from a neutral atom, forming a positively charged ion. It is a measure of how strongly an atom holds onto its electrons, and it generally increases across a period and decreases down a group in the periodic table.
When a moving car slows down it's kinetic energy decrease?
When a moving car slows down, its kinetic energy decreases because kinetic energy is directly related to an object's speed. As the car decelerates, its speed decreases, causing its kinetic energy to decrease as well. This energy is ultimately transferred into other forms, such as heat generated by the brakes.
How IS The electronegativity trend relates to the first ionization energy trend?
Electronegativity and first ionization energy both increase going up the Periodic Table.
In ionization energy how does the property varies within a group?
The ionization energy decrease moving down in a group.
Does the first ionization energy increase or decrease when you go down a group?
it increases
What is ionization energy and how does it relate to the periodic table?
The ionization energy is the energy needed to extract an electron from an atom.The value of the ionization energy increase from left to right in a period of the periodic table and decrease in a group from the above to down.
What is the group trend in the first ionization energies and why?
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
Which element has a lower first ionization energy than aluminum (Al)?
The element that has a lower first ionization energy than aluminum (Al) is magnesium (Mg). Magnesium is one period above aluminum on the periodic table, and as you move down a group or family, the ionization energy 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 are the metallic trends concerning electronegativity and ionization energy?
Electronegativity decrease going down in a group and increase from left to right; but this isn't a general rule.A similar situation is also with the ionization energy.
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
Which property has a trend similar to that of electronegativity?
First ionization energy has a trend similar to that of electronegativity.
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
Elements belong in upper ionization energy?
All of the elements on the top half of the periodic table belong in upperionizationenergy because the trend is top to bottom. Top being lowest and getting bigger as it goes down.------------------------------------------------------* In a group: the ionization energy decrease from the lighter elements to heavier elements.* In a period: the ionization energy increase from the left elements to the elements of the right.* When the atomic radius decrease the ionization energy increase.
