Why was Evidence of the existence of neutrons not come until many years after the discoveries of the electron and the proton why?

Electrons and Protons have a charge, which can be detected in a magnetic field.
However, neutrons, as the name suggests, are neutrally charged (no charge). So neutrons would not be detected in a magnetic field.

∙ 13y agoNeutrons eluded discovery until the 1930's because they have no charge and could not be manipulated in electric or magnetic fields.

∙ 13y agoThat is because neutrons don't have a charge, only mass. Protons had both and electrons had to be their 'mass'-less counterparts.

How many protons and neutrons and electrons are in H?
There are 1 proton, 0 neutron and 1 electron in H1.
How many neutrons and electrons does hydrogen en have?
Hydrogen has 1 electron, (1 proton) and 0 neutrons.
How many Protons Neutrons Electrons hydrogen have?
A hydrogen atom has 1 proton and 1 electron regardless of the isotope.Standard hydrogen(protium) has zero neutrons.The deuterium isotope has 1 neutron and the tritium (very radioactive) has 2 neutrons.
What are the three particles found in atoms?
The three main particles in atoms are a proton which is a positive charge, electron which is a negative charge and a neotron which has no charge at all. Tahlia :)
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
Who predicted neutrons 12 years before their existence?
Nobody did. Neutrons have always existed. Earnest Rutherford suggest neutrons might exist about 11 years before their existence was proven.
What has 12 neutrons and 1 electron in the 3rd level of the periodic table?
Sodium has 1 electron in the third energy level. 11Na23 isotope has 12 neutrons.
What is an electron cloud made of?
An electron cloud is made up of protons and neutrons.
How many protons neutrons and electrons are in hydrogen?
Hydrogen - 1 proton, 1 electron Deuterium - 1 proton, 1 neutron 1 electron Tritium - 1 proton, 2 neutrons, 1 electron
Does an electron cloud model show neutrons?
No
What kinds of evidence is used to support the theory that matter is composed of atoms?
Discoveries of physics in the 20th century: electrons, protons, neutrons, radioactivity, nuclear reactions, atomic force microscopy and many others.
What is the number of protons neutrons and electrons does helium have?
1 Proton and 1 electron but no neutrons.
Protons neutrons and electrons of hydrogen?
1 proton, 0 neutrons, 1 electron
What discoveries using radiation led to the modern understanding of atoms?
Charge of an electron, Size of an atomic nucleus, nucleus is positive, helium is alpha radiation, protons, neutrons, instability, radioactivity, and use for nuclear energy. And more
What are protons neutrons and electron charges?
Proton: Positive Neutron: No charge Electron: Negative
The number of neutrons that hydrogen has?
Hydrogen has no neutrons. It has 1 proton in the nucleus and 1 orbital electron.
Where are protons and neutrons found in an electron?
Protons and neutrons are not in electrons. protons and neutrons are the center or core of an atom. the electron(s) is/are found in a "cloud" along the outside edge of the atom. Hydrogen for example has 1 proton at its center and 1 electron floating around it keeping it neutral.
