yes
K refers to potassium. it is placed in alkali metal family i.e. group 1. Calcium is placed in alkaline earth family i.e group-2.
no. it is not in the same metal family
No, K is potassium; calcium is Ca.
prety sure that only Potassium (K) and Sodium (Na) can react with calcium. check the reactivity series for more info.
calcuim oxygen carbon
Yes. They are because they are both are in the same group and are metals.
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
Magnesium is an alkali earth metal. Beryllium and calcium are also alkali earth metals.
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Calcium hydroxide is a solid at room temperature. It becomes a liquid when heated above 1000 K. The melting point of calcium hydroxide is more than 3000 K.
The ions that have the same electron configuration as Argon (Ar) are the potassium ion (K⁺) and the calcium ion (Ca²⁺). Both of these ions lose electrons, resulting in an electron configuration that matches that of Argon, which is 1s² 2s² 2p⁶ 3s² 3p⁶. K⁺ has one less electron than neutral potassium (K), while Ca²⁺ has two fewer electrons than neutral calcium (Ca).
the last I heard they were callee Iron, Fe calcium, Ca and potasium, K
