Hydrogen has three naturally occurring isotopes, Protium, Deuterium, and Tritium. Protium has none, Deuterium has one and Tritium has two neutrons in its nucleus. Protium (Hydrogen-1) is found most abundantly in nature about 99.98 %. The remaining two isotopes are very rare as compare to Protium (Hydrogen-1). so, we can easily say zero.
How many electrons does hydrogen have?
Hydrogen is the first element of the periodic table and it has one electron in its shell. The number of electrons is always equal to the number of protons in an electrically neutral atom. Hydrogen has one proton as well as one electron.
What is hydrogen peroxide?
Hydrogen peroxide is a chemical compound, it has the formula H2O2. It is slightly denser than water and has a pale blue color in its pure form. It is used as an antiseptic and as a bleaching agent. It can decompose in the presence of light so, it is stored with a stabilizer and kept in a dark place. It will undergo thermal decomposition if heated above 150.2 °C (302.4 °F). It has a boiling point higher than water because of the hydrogen bonding.
How many valence electrons does hydrogen have?
The atomic number of the hydrogen atom is one, an electrically neutral hydrogen atom has one proton and one electron. Hydrogen is the first element of the periodic table and it has an electronic configuration of 1s1, meaning that it has one electron in its orbit or shell.
