Where are the nucleus and electron cloud found in a atomic structure?
The nucleus is found at the center of the atom and the electron cloud is found orbiting the nucleus at fixed, quantified radii.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
How can you use the periodic table and electron configurations to predict relative atomic radii and ionization energies for two atoms?
in a periodic table1>from left to right across a periodic tableionization energy increases & atomic radii decreases2>from top to bottom along a groupionization energy decreases and atomic radii increaseswhen considering the periodic table from left to right the main energy level is the same,but the number of electrons and protons increases.so the nuclear attraction increases and thus the electrons are pulled closer towards the nucleus.this decreases the atomic radii and increases the amount of energy needed to remove the electron in the outer most shell from the strong attraction.that is the ionization energy increases and atomic radii decreases when going from left to right across the periodwhen going down the group in a periodic table the electronic configuration of elements increases by 1 shell.that is the number of main energy levels increases.so the nuclear attraction between the atomic nuclei and the last electron decreases due to the increase in the distance.therefore it is more easier to remove the electron in the outer most shell of an element than that of the element immediately above it.therefore the ionization energy increases down the group.and since number of energy levels increases the atomic radius increases.
In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
What is the correlation of ionization energies to atomic radii for the elements?
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
Where are the nucleus and electron cloud found in a atomic structure?
The nucleus is found at the center of the atom and the electron cloud is found orbiting the nucleus at fixed, quantified radii.
Atomic radii cannot be measured directly because the electron cloud surrounding the nucleus does not have a clearly defined?
Outer Edge
How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
What is the difference between atomic radii and ionic radii?
atomci radii measures for an atom ionic radii measures for an ion
How can you find out the atomic radii?
Look for a reference chart in a book or online. Look for a Periodic Table of the Elements that has the atomic radii on it.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
Why standard reduction potential of potassium rubidium and cesium are nearly same?
they belong to group I and almost have same atomic radii and they have same tendency to lose electron.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
