1b) the atom could lose its valence electron
c) protons are equal to electrons so there is no need to include it
d) the atom would need to gain electrons to fill its valence shell to become negative
Answer:
A
Explanation:
As the interest rate goes up, your payments and the total repayment amount could increase. On the other hand, if the interest rate happens to drop, you may save money overall and pay less.
infiltration and evaporation
Answer: Option (D) is the correct answer.
Explanation:
The given elements Li, C and F are all second period elements. So, when we move from left to right across a period then there occurs increase in number of valence electrons as there occurs increase in total number of electrons.
So, it means more electrons are added to the same energy level.
Thus, we can conclude that a property of valence electrons for each element is located in the same energy level is common in the given elements.
