Why should you take index number as 100?
Working out percentage change from the base period is then simple.Working out percentage change from the base period is then simple.Working out percentage change from the base period is then simple.Working out percentage change from the base period is then simple.
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
What is change in velocity in a given period of time?
Acceleration
Change in velocity in a given period of time?
acceleration
If the length of a simple pendulum is doubled what will be the change in its time period?
ts period will become sqrt(2) times as long.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
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.
How does the ionization energy change at the start of each new period of elements?
The ionization energy generally increases at the start of each new period of elements. This is because as you move across a period from left to right, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons, making it harder to remove an electron.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
Does arsenic have the highest ionization energy?
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
Which elements has the highest ionization energy?
The noble gases typically have the highest ionization energies on the periodic table. This is because they have a full outer electron shell, making it difficult to remove an electron due to the stable electron configuration. Within the noble gases, helium usually has the highest ionization energy.
Elements belong in upper ionization energy?
Elements in the upper ionization energy range typically have a higher ionization energy due to increased attraction between the outermost electrons and the nucleus. These elements are often found in the right side of the periodic table, as they have a larger number of protons pulling on the electrons in the outer energy levels. Elements with high ionization energy tend to be nonmetals and have stable electron configurations.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Why does the first ionization energy generally increase across a period for the main group elements?
The first ionization energy generally increases across a period for main group elements because as you move from left to right across a period, the effective nuclear charge increases, making it harder to remove an electron from the outer shell. This results in a higher energy requirement to remove an electron, leading to an increase in ionization energy.
What is the exception to the trend of increasing ionization energy across a period in the periodic table?
The exception to the trend of increasing ionization energy across a period in the periodic table occurs when transitioning from group 2 to group 3 elements. This is because the group 3 elements have a slightly lower ionization energy compared to the group 2 elements due to the added stability of having a half-filled or fully-filled subshell.
Which element in the fifth period has the highest ionization energy?
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
Which has a greater ionization energy beryllium or germanium?
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
