The number of valence electrons an element has changes often, so we cannot use the periodic table to predict the number of valence electrons an element
has
True
False


Sagot :

Answer:

False

Explanation:

The number of valence electrons on an element is also the same or else it would be a different element.

The statement that the periodic table cannot be used to predict the number of valence electrons  is: FALSE

The number of valence electrons an element has will always remain the same for the element to remain the same element, elese the element will changes with a change in valence electrons.  therefore we can use the periodic table to predict the number of valence electrons that an element has.

A valence electron is an electron that is located in the outermost shell of an  atom or element. It is negative and it is used for the formation of bonds between atoms or elements.

Hence we can conclude that The statement that the periodic table cannot be used to predict the number of valence electrons  is: FALSE .
