Why does Cs Ba Sr have a low electron affinity?
Cs (cesium), Ba (barium), and Sr (strontium) have low electron affinities primarily due to their large atomic radii and low effective nuclear charge experienced by valence electrons. As alkali and alkaline earth metals, they tend to lose electrons rather than gain them, making the addition of an electron less favorable. Additionally, the energy required to add an electron to these elements is often less than the energy released during the process, leading to low or even positive electron affinity values.
How many valence electron does Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What ions does not have a noble gas electron configuration S 2 Sr 2 you Cs or Be 3?
Be3+ has only 2 valence electron and not 8.
When Sr and F combine to form a compound which atoms will become an anion?
The fluorine. 2F - SrF2 ======the compound
What is the electron dot notation for phosphorus and strontium?
Ah, let's paint a lovely picture of electron dot notation for phosphorus and strontium. Phosphorus has 5 valence electrons, so its notation is P with 5 dots around it. Strontium has 2 valence electrons, so its notation is Sr with 2 dots around it. Remember, each dot represents an electron sharing its positive energy with the world.
Which element has the lowest electron affinity Is it nitrogen?
No, nitrogen does not have a low electron affinity. Electron affinity increases as you go up and to the right on the periodic table. Thus, Groups I and II elements (ex. Cs, Ba, Sr, etc.) have LOW electron affinities and the halogens in Group VII (Br, Cl, F, etc) have the HIGHEST electron affinities. Chlorine has the HIGHEST electron affinity on the periodic table.(Fluorine is an exception in this case.)
Why does Cs Ba Sr have a low electron affinity?

What are the differences between active low and active high SR flip flop?
Hello The difference between an active low and an active high SR flip-flop is that with the active low SR flip-flop, the system is activated when the inputs to system are zeros while with the active high SR flip-flop, the system is activated when the inputs to the system are ones.
Which atom is bigger Mg or Sr?
Sr (strontium) is bigger than Mg (magnesium) because as you move down a group (in this case, group 2 of the periodic table), the atomic size generally increases due to the addition of more electron shells. Sr, being lower in the group, has more electron shells compared to Mg.
How many valence electron does Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What layer of atmosphere did the SR71-Blackbird fly in?
The SR-71 Blackbird primarily operated in the stratosphere, which is the second major layer of Earth's atmosphere. This layer is characterized by high altitudes, low air pressure, and stable atmospheric conditions - ideal for high-speed, high-altitude flight capabilities of the SR-71.
When was Ismael Mathay Sr. High School created?
Ismael Mathay Sr. High School was created in 1971.
How many electrons do Sr have?
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
What is Sr noble gas configuration?
The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
What actors and actresses appeared in High and Low - 1913?
The cast of High and Low - 1913 includes: Pauline Bush as Undetermined Role James Harrison as James Calvin Jr. George Periolat as James Calvin Sr. Jack Richardson as Charles Bergen
What ions does not have a noble gas electron configuration S 2 Sr 2 you Cs or Be 3?
Be3+ has only 2 valence electron and not 8.
Purpose of the SR-71 Blackbird?
The SR-71 is a high-altitude, high-speed reconnaissance aircraft. It carries high performance cameras used in spying.
