Explanation:
it exists as atom or ion but not as sodium molecule. So there is no any sodium sodium bonding between two sodium atoms. Sodium combines with other element or group to form compounds of sodium like sodium chloride ,sodium carbonate ,sodium sulphate etc. Sodium has symbol Na and its atomic no. is 11 .
Answer: A thermal conductor is a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself.
Explanation:
In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.
Answer:
Explanation:
Since 1 mole of Fe reacted and 1 mole of Cu is produced.
Mass = molar mass × number of moles
Molar mass of Fe = 56 g/mol
Molar mass of Cu = 63.5 g/mol
Mass of Fe = 56 × 1
= 56 g
Mass of Cu = 63.5 × 1
= 63.5 g
Therefore, the statement is not correct.
