The isotope of hydrogen we call tritium is radioactive because all atoms of it have an unstable nucleus. Tritium, which is hydrogen-3, has a single proton in its nucleus (as you'd expect), and has two neutrons there as well. This combination of nucleons is not stable, and it will eventually decay (with a 12.32 year half-life). Said another way, the nuclear arrangement of a proton and two neutrons is not a stable one, so atoms of this isotope of hydrogen will be radioactive and will eventually decay.
When any atom is "created" by fusion or other means (including nuclear decay), the nucleons (the protons and neutrons that make up its nucleus) have to "make a deal" as to how they are going to get along in the tiny volume of space that the nucleus occupies. Some arrangements of protons and neutrons just "aren't right" and are unstable, and this gives rise to characterizing the isotope as being radioactive. Tritium (H-3) is one such isotope.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
No, the symbol "H" stands for Hydrogen on the periodic table. The symbol "He" stands for Helium on the periodic table.
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
These names are the names of chemical elements.
Si is the abbreviation for silicon on the periodic table.
No; T may be a symbol for the tritium an isotope of hydrogen.
Elements at the extreme ends of the periodic table: high end - uranium, plutonium; low end - hydrogen (deuterium & tritium), lithium.
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
A group in Periodic Table is the column of element in periodic table
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
It is called the Periodic Table of Elements.
There are no compounds on the periodic table. The periodic table only lists elements.
who introduced the first Periodic Table
No, the symbol "H" stands for Hydrogen on the periodic table. The symbol "He" stands for Helium on the periodic table.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
