1.	In the laboratory , sodium choride is made by burning the sodium in the atmosphere of cholrine which is yellow in colour .The cause of yellow colour isA. Presence of `Na^(+)` ions in the crystal latticeB. Presence of `Cl^(-)` ions in the crystal latticeC. Presence of electron in the crystal latticeD. Presence of face centered cubic crystal lattice
Answer» Correct Answer - c Yellow colour on heating `NaCI` in the presence of Na is due to presence of electron in ation vacancies (f-centres).
