hydrogen isotopes

All isotopes of the same element have the same number of protons, but a variable number of neutrons. The isotopes of hydrogen have the following structures (Fig.9.1)...

Atoms of the same element having the same atomic number but different mass numbers are called isotopes. The nuclei of these atoms have same number of protons but different number of neutrons. All the properties of the isotopes depending upon mass are different. Differen..

Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at three separate places. ..

Hydrogen atom (Z = 1) has no neutrons. Number of protons = 1Number of electrons = 1Number of neutrons = 0It has been reported that the hydrogen element has atoms with mass number 2 and 3 also i.e., Atoms of elements having the same atomic number with different mass nu..

Summary - Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combin..

1. The classification of elements is based on the atomic number, which is a more fundamental property. 2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic numbe..

The sun is the most enormous and direct, source of energy. Where does this enormous energy that the sun radiates come from? The source of this energy was not known to mankind until the year 1939. It was a German physicist, Hans Bethe, who proposed that the sun contains hydrogen nuclei in ..

g - rays emitted by the radioisotopes can be used in the treatment of cancer. These radiations tend to destroy cancerous cells and the way can arrest the spreading of the cancerous cells. 6 0 CO is used in the treatment of tumours and cancers...
