How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
Why does an atom with only one electron in its valence shell make a better conductor than an atom with seven electrons in its valence shell?
An atom with only one electron in its valence shell is more likely to lose that electron easily, making it a better conductor. In contrast, an atom with seven electrons in its valence shell is more stable and less likely to lose electrons, thus making it a poor conductor.
Which valence electron level has the greatest amount of reactive energy and the maxium amount of electrons found in each level?
The valence electron level with the greatest amount of reactive energy is typically the outermost shell, which corresponds to the highest principal energy level (n). This level can hold a maximum of 8 electrons, following the octet rule for main group elements, although the first energy level can only hold 2 electrons. Elements with fewer electrons in this level tend to be more reactive, as they seek to achieve a stable electron configuration. The reactivity generally increases as you move down a group in the periodic table, particularly for alkali and halogen elements.
How you can remove electron from atom?
Simplest method - apply a voltage to a conductor.
How many valence electrons does lithium have?
Lithium has only one valence electron. A valence electron is an unpaired electron available for bonding with other elements. This makes lithium is a highly reactive element that can bond rapidly and often violently with any element having four to seven valence electrons (or with hydrogen).
What is the total amount of electrons and valence electrons in francium?
Francium has 87 electrons; one is the valence electron.
How can you determine the number of valence electrons in an atom?

What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
Which atom in the ground state requires the least amount of energy to remove its valence electron?
b
How many valence electrons in H2 atom?
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
How to find the amount of valence electrons in an atom?
To find the amount of valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
Why does an atom with only one electron in its valence shell make a better conductor than an atom with seven electrons in its valence shell?
An atom with only one electron in its valence shell is more likely to lose that electron easily, making it a better conductor. In contrast, an atom with seven electrons in its valence shell is more stable and less likely to lose electrons, thus making it a poor conductor.

What is the electron dot method for Na and Br?
The electron dot method, also known as Lewis dot structure, represents the valence electrons of an atom. For sodium (Na), there is one valence electron, represented as a dot. For bromine (Br), there are seven valence electrons, six of which are represented as dots surrounding the Br symbol, with one dot paired on one side.
How many electrons are on the outer shell of lithium?
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
Do elements in the same group have the same amount of electron clouds?
No, they do not. However, elements in the same group have the same number of valence electrons.
