Caesium and potassium are similar alkaline metal elements.
As you go down the periodic table, elements become less reactive. Therefore, potassium (K) is more reactive than cesium (Cs) because cesium is located further down the group compared to potassium.
Potassium (K) has a more metallic character compared to Silicon (Si). This is because potassium is an alkali metal with more metallic properties such as high electrical conductivity, luster, and malleability, while silicon is a metalloid with properties that are in between metals and nonmetals.
SI unit for temperature is K. K stands for Kelvin
Of the elements listed by atomic symbol, Cs has the largest atoms.
K
The correct symbol for the SI unit of temperature is K (kelvin).
Yes, rubidium (Rb) is more reactive than lithium (Li), potassium (K), sodium (Na), and cesium (Cs). In the alkali metal group, reactivity increases as you move down the periodic table due to the increasing atomic size and the decreasing ionization energy, which makes it easier for the atoms to lose their outermost electron. Thus, Rb, being below K and Na, is more reactive than all of them. However, cesium (Cs) is even more reactive than rubidium.
The SI unit for temperature is the Kelvin, symbolized as K.
Kelvin is the SI units temperature measurer. the symbol is a capital k, K
The ionization energy increases from Cs to K to Li. This is because as you move from left to right across a period in the periodic table, the effective nuclear charge increases, leading to a stronger attraction between the outer electrons and the nucleus, thus requiring more energy to remove an electron.
Kelvin is the SI unit for thermodynamic temperature. symbol: K (there are no degrees, unlike °C and °F).
The official SI unit is the kelvin (K).
