Which of the following group is NOT Dobereiner Triads?

 

Group 1 metals are also called as alkali metals with reactive in nature and low melting points. They are soft and produce hydrogen and alkaline metal hydroxide solution when they react with water.

German Chemist, Adolf von Baeyer first synthesized Barbituric Acid in 1864.

Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms. Atoms are more stable when they have full valence shells.

The ionization energy decreases from top to bottom in groups, and increases from left to right across a period.

HGence, in this trend Francium (Fr) has the lowest ionization energy.

True, The luster of a metal is due to presence of free electrons. Luster means shine or soft glow. We know that metals have the quality of reflecting light from its surface.

The compound MgCl2 is named as Magnesium Chloride.

Radioactive decay is likely to occur when the nuclei of an atom doesn't have enough binding energy to hold the nucleus together due to excess of rotons or nutrons in it.

One turn of the citric acid cycle produces

1. Two molecules of carbon dioxide are released.

2. One molecule of ATP or GTP is produced.

3. Tree molecules of NADH and one molecule of FADH2 are generated.

Semiconductors are those materials that are neither good conductors nor the good insulators of heat and electricity. Silicon (Si), Germanium (Ge) and Cadmium Sulphide (CdS) are semiconductors which work as conductors in some special conditions only.
