Access supporting teaching materials on atomic radius here: www.teacherspayteachers.com/P... In chemistry, we all memorize that atomic radius increases as you go down a group and decrease as you go across periods. Ever wonder why?
Thank you so much for that. We truly appreciate your support. We're currently working on our next video on chemical bonding. It should be out by the end of September ☺️
This video really helped me!!! I hope your not getting discouraged by your lack of success and not making videos, the animation style is amazing and the explanation is clear.
Am watching it in 2023.. And it is really helpful for me..... To vanish my confusion..... Thnkuu so much..... Greatfull.. Easily and beautifully described ❤️❤️❤️❤️👌.....
Now i understand protons pull electrons close making the atom smaller in size. The more atoms the more smaller the smaller the atom is. Periods and little amount of protons make them bigger. Thank you
Thank you sooo much . Definitely Clearer now , in the span of 3 minutes. Quick question inside the nucleus you have 3 red protons what do the orange circles signify ? Sorry doe the silly question 🙈
But why does nuclear charge matter? In atoms, the number of electrons always = number of protons, so really this attraction should "cancel out", right? In ions, there may be fewer electrons than protons, in which case yes, the positive charge will be greater than the negative charge, giving an overall attraction towards the nucleus. But what about atoms then?
But why down the group atomic radius increases? it should deacrease cuz as we move down the group the atomic size increases there will be more electrons so, more effective nuclear charge... So why does it decrease?
