Which atom has higher shielding effect,Li or Na? - Brainly

WebApr 4, 2024 · This effect is observed in an atom having more electrons and particularly more electron shells. The electrons in the valence shell are attracted by the positively charged nucleus. While there is repulsion between the valence electrons and the electrons present in the inner shells. WebThe shielding effect describes the balance between the pull of the protons on valence electrons and the repulsion forces from inner electrons. The shielding effect explains … WebReset Help eight Li has proton (s), and has proton (s). 8+ one Both atoms have two electrons that predominately contribute to the shielding, while the electrons will contribute a slight shielding effect. 6+ Thus, lithium has an effective nuclear charge of slightly more than and oxygen has oxygen an effective nuclear charge of slightly more than ... iosh managing safely course london

WebMar 23, 2016 · Which of the following elements would exhibit the greatest shielding effect? A. Lithium B. Sodium C. Potassium D. Rubidium See answers ... Answer: Option (D) is the correct answer. Explanation: Shielding effect is the effect in which nucleus of an atom is surrounded by number of electrons in such a manner that there will be decrease in ... WebSodium has 11 protons and argon has 18 protons. Each time we add a proton to a the nucleus the electron (which are negatively charged) feel a greater attraction to the nucleus. Since valence electrons are all in the same level, they feel a greater attraction to the nucleus as we move across the period.

WebHence, despite there being more positive charge, the amount of that charge that gets felt by the valence electron decreases because the distance between them has increased. It turns out, this increased distance which lowers Zeff outweights the increased Zeff from additional positive charge from the nucelus. Hence, Zeff decreases down a group. WebDec 1, 2024 · Therefore it is easier to remove the most loosely held electron because the atom is larger with a greater shielding effect which means that the nucleus has less control over potassium's outer electron, 4 s1 . Therefore IE1 for potassium (418.7 kJ/mol) is less than IE1 for lithium (520 kJ/mol).

WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2. WebThe shielding effect is shown by the interior electron cloud (light blue) shielding the outer electron of interest from the full attractive force of the nucleus. A larger shielding effect …
