Why ionization energy decreases down the group and increases along a period?
Going down a group, the number of valence electrons remains the same, but these electrons get farther and farther away from the nucleus. Thus, they are not as tightly held and the ionization energy decreases. Moving from left to right along a period, the electrons are the same distance from the nucleus, but the number of protons are increasing in the nucleus, thus holding those electrons more tightly. Thus, the ionization energy increases.
Where does electron exist in an atom?
Electrons exist in the electron cloud that surrounds the nucleus of an atom. This cloud is made up of the various orbitals that hold the electrons. Orbitals are regions of space in which the probability of finding an electron is the highest. The electrons orbit the nucleus in these orbitals and can move from one orbital to another as they gain or lose energy. 1s Orbital: This orbital is closest to the nucleus and can hold up to two electrons. 2s Orbital: This orbital is farther away from the nucleus and can hold up to two electrons. 2p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3s Orbital: This orbital is farthest away from the nucleus and can hold up to two electrons. 3p Orbitals: These orbitals are even farther away from the nucleus and can hold up to six electrons. 3d Orbitals: These orbitals are the farthest away from the nucleus and can hold up to ten electrons.These orbitals are filled in a specific order with the 1s orbital being filled first then the 2s 2p 3s 3p and finally the 3d orbitals. The electrons in the outermost orbitals are called valence electrons and are responsible for the chemical properties of the atom.
When electrons gain additional energy do they move farther away from the nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in. These "outer" electrons are said to be in higher Fermi energy levels, and they have more kinetic energy than the electrons in lower orbitals. Consider that electrons give up energy to "fall into" closer orbitals, and they will, in general, have less energy than the outer electrons. A consequence of the idea that there is less energy binding outer electrons to that nucleus is that it takes less energy to remove that outer electron from an atom. These are the so called ionization energies of the atom's electrons. And when the electron is in a higher orbital, it has a lower ionization energy. It can be removed more easily. As we attempt to remove more electrons from that atom, it takes progressively more and more energy as we move inward removing electrons.
The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?
To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
What particles might be found in shells around a nucleus?
The particles found in the area surrounding the nucleus are called electrons. Electrons are attracted to the protons in the nucleus, but are repelled from other electrons. This is why they can be found orbiting the nucleus.
Electrons farther from the nucleus are said to be of what energy?
higher energy
How bohr atomic theory differ for ratherfood atomic theory?
Rutherford said there was a heav, positively charged nucleus with lots of empty space around it in which there were electrons. Bohr went farther and said the electrons were in exact orbits around the nucleus. The electrons could not be just anywhere in that empty space, but only in those exact orbits (orbitals).
The farther an energy level is from the nucleus the bigger is its what?
You must be thinking of electrons in shells surrounding the nucleus. The quantity getting bigger is therefore the diameter of the electrons orbit.
Do attractive forces have less hold on electrons farther from the nucleus?
Yes, as electrons get farther from the atomic nucleus they are less attracted to that nucleus, which is exactly what you would expect on the basis of Coulomb's Law, F=q1q2/r2 as the radius of the orbit increases the attractive force becomes decreased.
Which has more potential energy an electron close to an atomic nucleus or one far from an atomic nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in.
Why do you suppose that an energy level close to the nucleus can hold fewer electrons than one farther away from the nucleus?
it has to do with quantum numbers N,L, and M
Why large atoms are more likely to lose electrons?
In simplistic terms, an atom's electrons are held tot he atom because they are attracted to the positively charged nucleus. In larger atoms the electrons are farther away from that nucleus and there are usually more electrons in between, resulting in a weaker attraction.

The farther an electron is from the nucleus the?
The farther an electron is from the nucleus, the greater its energy.

Valance electrons are furthest from the nucleus.
