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.
Does the electron determine the reactivity of an atom?
Outer, or valence, shell electrons do.
How can you determine the number of valence electrons an atom has?
The valence is determined experimentally.
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.

What do valence electrons determine about an element?
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
How can you determine the number of valence electrons in an atom of a representative?
To find the number of valence electrons in an atom of a representative element, all you have to do is look at its group number. Ex: Group 1 (Hydrogen, Lithium, Sodium, Potassium, ect.) All have 1 valence electron.
What subatomic particles determine the charge of an atom?
The electron. The electron is has a negative charge. The more electrons that are in a valence shell of the atom the more negative the atom will be.
What do the electrons in an electron dot structure represent?
It represents the number of valence electrons in the atom.
What is the valence electron number in an atom?
the number of electrons in the 3rd energy level of an atom.
how number of valence electrons sodium have?
A sodium atom has one valence electron.
How an atom valence electrons configuration determine its place on the periodic table?
the valence electron number equals the group number. the principal energy level equals the period number it's located in.
How many valence electron can any atom have?
The number of valence electrons depends on the atom and can vary from 1 to 8.
How can you determine the number of valence electrons an atom has?
The valence is determined experimentally.
