What evidence led J.J. Thomson to believe that atoms of all elements contain electrons?

all atoms in this universe reacted to each other and form chemical bond with the help of electrons.the inter-molecular forces also depend on electrons because these forces of attraction between two molecules are made by two poles negative (electron) and positive(proton)
if electrons are not present in all atoms .so all atoms have positive charge and no one atom reacted to each other and form chemical bond. so, no matter is present in this universe except positive charged particles.

What type of bond does NO2 have?
covalent, because the elements are both nonmetals. If it was a metal it would be a ionic bond.
What elements bond with noble gases?
You may have to forgive me if I'm wrong but i'm about 98% sure. Nothing bonds with the noble gases. The noble gases are just that....their too good for the other elements and won't mix with them. The real reason for this is that the noble gases all have the max number of electrons they can take one. Which I believe to be 8. Chemical reactions are what happens when two elements that have exchange electrons. For example: 2 atoms of hydrogen each with 1 electron when combines by nuclear fusion result in helium, which has 2 electrons.
How many elements when mendeleeve made his periodic table?
I believe there were 55 or 56 known elements then.
What elements would it be easier to remove two electrons from?
The halogens (group 17) and the alkali metals (group 1) combine to make full-shell compounds. The noble gases, group 18, already contains full shells and does not bond easily because of this.
What is the word for strong attraction to electrons as do the atoms of oxygen and hydrogen.?
electronegativity, i believe
Name of tompsons theory of what an aom looked like?
I believe it is known as "Thomson's Model" or "Thomson's Atomic Model"
What experimental evidence led to bohr to believe that electrons can posses only specific amounts of energy?
The line spectra produced by excited atoms
What element is a alkaline metal and has 2 electrons?
The element (neutral atom) with two electrons would be helium, which is a noble gas. I believe the question you are asking is, what element is an alkaline earth metal with 2 valence electrons? The answer to that question is, there are a half dozen of these elements in Group 2A. The two most commonly known elements are magnesium and calcium.
Kim Thomson what year was she born?
Kim was born in 1960. Can you believe it!
What type of bond does NO2 have?
covalent, because the elements are both nonmetals. If it was a metal it would be a ionic bond.
What evidence suggest that ghosts are imagined?
What evidence suggest ghosts are real? I believe that is the evidence.
What do the electrons do in a covalent bond?
I believe they would be sharing electrons in the outer orbit.
What are the electrons doing in a covalent bond?
I believe they would be sharing electrons in the outer orbit.
How many electrons can be on level 3?
I believe its 18 electrons on the 3rd orbital shell
What are electrons doing in a covalent bond?
I believe they would be sharing electrons in the outer orbit.
Is there any evidence of ghosts?
There is no scientific evidence. Those who believe in ghosts will put forward non-scientific evidence.
What are the elements that have 3 or fewer valence electrons called?
All the elements in the first column of the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium) have one valence electron. I also believe Helium has one valence electron.
