What else can I help you with?
Why isotopes have only proton and different electron?
Isotopes have a different number of neutrons.
How are isotopes of hydrogen same?
All hydrogen isotopes have a proton and an electron; the number of neutrons is different.
How many isotopes of hydrogen are known?
Three isotopes: Protium, deuterium and tritium with 0, 1 and 2 neutrons. all isotopes have 1 proton and 1 electron.
Who discovered that atoms contain subatomic particles?
J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.
Does an electron or proton have a larger charge?
No. The electron and proton have the same amount of charge. Its just that the electron's charge is negative and the proton's charge is positive.
Why isotopes have only proton and different electron?
Isotopes have a different number of neutrons.
How are isotopes of hydrogen same?
All hydrogen isotopes have a proton and an electron; the number of neutrons is different.
Which was discovered first proton or electron in which year and by whom?
the electron was first discovered in 1897 by Joseph john Thomson and the proton was discovered in 1913 by ernest Rutherford
How many isotopes of hydrogen are known?
Three isotopes: Protium, deuterium and tritium with 0, 1 and 2 neutrons. all isotopes have 1 proton and 1 electron.
What do two different neutral Isotopes have the same elements in common?
The proton and electron number are equal for all isotopes of the same specific element.
What is the number of protons electrons and neutrons in platinum?
the number of proton neutron and electron proton(+p) and electron(-e) has 78 and neutron has 116, 117, or 118 (or from 112 to 120, including synthetic isotopes)
What was J. J. Thomson contribution?
JJ Thompson discovered 'the electron in 1897 and he also discovered 'the proton'
Isotopes of the same element differ in the number of what-?
Only the neutron number is different, same proton and electron number.
Who discovered the subatomic particles and in which order?
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 Neutron: James Chadwick, 1932
What is hydrogen 1?
Hydrogen exists as 3 isotopes: Hydrogen with 1 proton and 1 electron; Dueterium (also called Heavy Hydrogen) with 1 neutron, 1 proton and 1 electron, and Tritium having two neutrons, 1 proton and 1 electron. Note that all have 1 proton (i.e. the Atomic Number) being all the same element.
What particles does hydrogen contain?
Hydrogen contains one proton inside the nucleus and one electron revolving around the nucleus. Hydrogen has three isotopes namely protium, deuterium and tritium with 0, 1 and 2 neutrons respectively in the nucleus.
What are the isotopes of hydrogen atom?
The three isotopes of a hydrogen atom are protium (1H), deuterium (2H), and tritium (3H). Protium is the most common form of hydrogen and has one proton and one electron. Deuterium is a stable isotope with one proton, one neutron, and one electron. Tritium is a radioactive isotope with one proton, two neutrons, and one electron.
