Barium (502,9 kJ/mol) has a lower first ionization energy than beryllium (899,5 kJ/mol).
Be, due to complete '2s' orbital.
Ba
Generalization and Discrimination: even though the response is emitted, animals can be taught to discriminate between situations. A pigeon will learn that they will get a pellet when they press a lever... when they press the lever and there is a red light no (negative discriminative stimulus [S-]), when there is a green light yes (positive disciminative stimulus [S+]). In difference to CS- and CS+, the S+ and S- tells the animal the impact of their behaviour: no point in acting (S-) or act now to get reward (S+) versus the CS+ and CS- which mean no matter what the reward comes or does no (it is indifferent to the animal's behaviour. Same can be stated for generalization... animals will respond to similar stimuli if they are similar to original

The formula name for the element CsF is Caesium fluoride.
Alkali metals have increasing reactivity going down the group. Francium may not be considered as it is not a stable atom: it is radioactive. The next four are Cesium, Rubidium, Potassium and Sodium in decreasing reactivity order.
The alkali metal group easily lose their outermost electron. This group consists of lithium, sodium, potassium, rubidium, cesium, and francium.
Ionization energy increase from left to right. Ionization decreases going down a cloumn. Answer= Cs, K, Li
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Caesium has a smaller ionization energy (375,7 kJ/mol) than strontium (549,5 kJ/mol).
Cesium (Cs)
Atoms of alkaline metals: Rb, Cs, Fr, K, Na, Li. They have a low ionization potential. This potential is expressed in kJ/mol - molar ionization energy and is different for the first, second, third...n electron.
The population of CS Energy is 490.
CS Energy was created in 1997.
Hydrogen.
Cs (Caesium) is the most reactive!!!!
Caesium is the most reactive.
Ba and Cs
These elements are: K, Rb, Cs, Fr, Ra.
