Cesium (Cs) is more reactive than strontium (Sr). Both elements belong to the alkali and alkaline earth metal groups, respectively, but cesium is located further down the Periodic Table, which increases its reactivity due to its larger atomic radius and lower ionization energy. This makes cesium more likely to lose its outer electron and participate in chemical reactions.
What else can I help you with?
Are the properties of Rb more similar to those of cs or those of Sr?
Rubidium (Rb) shares more similar properties with cesium (Cs) than with strontium (Sr). Both Rb and Cs are alkali metals, which means they have similar chemical properties, including high reactivity and the tendency to form +1 cations. In contrast, strontium is an alkaline earth metal, exhibiting different reactivity patterns and a +2 oxidation state. Thus, Rb is more closely related to Cs in terms of chemical behavior and properties.
What is an akalide metal?
An alkali metal is a group 1 element, Li, lithium; Na, sodium; K,potassium; Rb, rubidium; Cs, cesium; Fr, francium. The alkaline earth metals are group 2 elements, Be, beryllium; Mg, magnesium; Ca, calcium; Sr, strontium; Ba, barium, Ra, radium
What elements where used to produced fireworks?
Compounds of Na, Cs, Rb, Cs, Sr, Li, Ba, Ca, K are used in fireworks; also elements in pure form as C, Fe, Ti, Al.
Element M reacts with chlorine to form a compound with the formula MCl2 It is more reactive than magnesium and smaller than barium This element is?
Element M is calcium. It reacts with chlorine to form calcium chloride (CaCl2). Calcium is more reactive than magnesium and smaller than barium on the 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.
What alkali earth metal is the most reactive Be or Sr?
Be (beryllium) is more reactive than Sr (strontium) among the alkali earth metals. Beryllium has a higher reactivity due to its small atomic size and high electronegativity, making it more likely to form bonds with other elements.
Why Sr hazardous to people?
Sr - strontium, is a highly reactive alkaline earth. It can react with moisture on the skin and other body parts to produce a very strong alkaline substance which will burn the skin. It is more reactive than calcium metal. It is also classed as a heavy metal.
Are the properties of Rb more similar to those of cs or those of Sr?
Rubidium (Rb) shares more similar properties with cesium (Cs) than with strontium (Sr). Both Rb and Cs are alkali metals, which means they have similar chemical properties, including high reactivity and the tendency to form +1 cations. In contrast, strontium is an alkaline earth metal, exhibiting different reactivity patterns and a +2 oxidation state. Thus, Rb is more closely related to Cs in terms of chemical behavior and properties.
What element is more active Sr or Ag?
Sr (strontium) is considerably more reactive than Ag (silver). In fact, Strontium is so reactive that it must be stored in mineral oil to prevent its reaction with the oxygen in the air. Strontium also reacts with water.
Which element would be most reactive be sr or ba?
Barium (Ba) would be more reactive than strontium (Sr) because barium is located further down the Group 2 elements in the periodic table. As you move down the Group, the reactivity of the elements tends to increase due to the larger atomic size and lower ionization energy, making barium more reactive than strontium.
What element in the 5th period is not a transition metal?
Sn (Tin) Is one reactive non-metal in period 5.
What does the abbreviation SR refer to in chemistry?
Sr is the abbreviation for Strontium - a chemical element (symbolSr and atomic number38). An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically.
Is the element Sb an alkali metal?
No, the element antimony is a member of group 15 with nitrogen, phosphorus, arsenic and bismuth. It is a semi-metal. You may be thinking of Sr, strontium, which is a highly reactive member of the alkali metals.
Which element has a smaller ionization energy Cs or Sr?
Cs has a smaller ionization energy than Sr. This is because Cs has a larger atomic radius and its valence electron is farther from the nucleus, making it easier to remove compared to Sr which has a smaller atomic radius and stronger nuclear attraction.
Chemical symbol element St?
The chemical symbol for the element Strontium is Sr. It is a soft, silvery metal that is highly reactive and is commonly found in minerals such as celestine and strontianite. Strontium is used in the production of fireworks, flares, and toothpaste.
Is SrCL2 a metal or non-metal elements?
SrCl2 is a compound and not a metal or non-metal. SrCl2 is made from a metal, strontium, Sr, and a non-metal, chlorine, Cl.
What are some alkali?
Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra.
