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?
these atoms offer the least amount of resistance for knocking the valence electron out of its orbit.
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
How you can remove electron from atom?
Simplest method - apply a voltage to a conductor.
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.
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.

Is sodium similar to lithium?
Sodium and Lithium are in the same group in the periodic table and tend to have similar properties, for example, adding a small amount to water will result in a "fizzing" type of reaction. Other elements in this group such as caesium react with water in a similar fashion only far more violently.
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
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 do you find the valence electron?
If you can find a dot diagram, look at the outer shell and count the electrons. The outer electrons is the amount of valence electrons.
How you can remove electron from atom?
Simplest method - apply a voltage to a conductor.
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
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.
Which information will be most helpful in determining the charge of the atom's nucleus?
The number of valence electron will be required. It will describe the amount of charge.
