What is the valence electron from hydrogen?
Hydrogen is usually 1 valance in a resting state but can be raised in number of valances with loading as in heavy water or tritium, helium are higher valances.
How does the energy of core electron compare with the energy of valence electron?
valence electrons are bound to atoms and are used to bind atoms into molecules. free electron are free, either they are in the conduction band "electron gas" of a metal or they are in a vacuum (perhaps in a vacuum tube).
What do you call an atom if you move an electron in an atom from a low energy level to a higher energy level within the atom?
When you move an electron in an atom from a lower energy level to a higher energy level, it is called an electron excitation. This process requires the electron to absorb energy to move to a higher energy state.
How does the number of valence electrons vary as the elements within the group increase in mass?
As elements within a group on the periodic table increase in mass, the number of valence electrons remains constant because elements in the same group have the same electron configuration in their outer shell. For example, all elements in Group 1 have one valence electron, while those in Group 2 have two, regardless of their mass. However, the increasing mass generally corresponds to higher atomic numbers and additional electron shells, but the valence electron count does not change.
Does each Transition Metal on the Periodic Table only have 2 valence electrons according to the electron configuration with subshells?
Because valence electron are always in the outer most layer (here the N number). You would think that the valence would come from the D orbital but if you look attentively, there will always be a S orbital with a higher N number. Example: Sc 1s2 2s2 2p6 3s2 3p6 4s2 3d1 The valence electron will always come from the 4s2 subshell, and as you go along the period, the electrons are going to add up only in the 3d orbital.
How does the energy of core electron compare with the energy of valence electrons?
The energy is higher.
What is an electron in the outermost energy level of an atom?
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons

How does the energy of core electrons compare with energy of valence electrons?
Core electrons have lower energy compared to valence electrons. Core electrons are located closer to the nucleus, experience a higher effective nuclear charge, and are more shielded by inner electron shells, leading to lower energy levels. Valence electrons are found in the outermost energy level and have higher energy due to their increased distance from the nucleus and lower shielding effect.

Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
The valence electrons in nitrogen are located farther from the nucleus and shielded by inner electron shells, resulting in an increased screening effect and a higher effective nuclear charge experienced by the valence electrons. In contrast, the valence electrons in beryllium are in a lower energy level closer to the nucleus, which leads to a weaker screening effect and a lower effective nuclear charge.

What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
The question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?This question may seem hard and/or confusing, but it's really not. You just have to think about it for a minute. This question was in my science quiz online. I had to take LOTS of notes, and guess what?, the answer was right there in my notes..The notes that I took for this question had the topic:Electrons in an ElementMy notes were:-Electrons occupy the electron cloud.-Each electron occupies an energy state.-Electrons farther from the nucleus occupy a higher energy state.-The electron cloud is divided into energy levels.-Each energy level can hold a certain number of electrons-Valence Electrons are usually found in the highest energy level.Not very much notes, but lots of information, and most of them are about energy, and one is about Valence electrons. So, let's figure this.If a valence electron usually have the highest energy level, then a nonvalence electron must not have any energy levels. So, what you would have to add to the nonvalence electron is add energy to become a valence electron.Our question is: What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?So the answer to our question is: Energy. Energy can be added.
Why does fluorine have a valency of 1?
the simple molecular structure allows higher concentration of electron to pass through freely
Why the first ionization energy of noble gas is higher than that of halogens?
The first ionization energy of noble gases is higher than that of halogens because noble gases have a full valence shell, making them very stable and less likely to lose an electron. Halogens, on the other hand, have one electron short of a full valence shell, so they have a stronger tendency to lose that electron and therefore require less energy to do so.
