Predict the electronegativity of the undiscovered element with Z = 119.

Video transcript

Hey everyone where ask is this statement true or false? The electro negativity of an unknown element with an atomic number of 120 will be very high. First. Let's go ahead and think about what we've learned based on our electro negativity trends in our periodic table. So as we move from left to right in our periodic table, we know that our electro negativity increases now as we move down a period, we know that our electro negativity decreases. Now if we look at our periodic table, we've learned that flooring with an atomic number of nine is going to be our most electro negative element. And when we look at Francy um with an atomic number of 87, we know that this is going to be our least electro negative element. Based on this information. If we had an unknown element with an atomic number of 1, 20 this means that our electro negativity will be relatively low. So this statement is actually going to be false And we can change it by saying the electro negativity of an unknown element with an atomic number of 120 will be very low. And this is going to be our final answer. Now, I hope that made sense. And let us know if you have any questions
