Does an electron contain many atoms?
A single electron contains no atoms; atoms contain electrons instead.
Does sulfur contain electrons?
Yes. All matter on Earth contains atoms and thus electrons.
Which part of the atoms contains most of its volume?
An atom's electrons are distributed through most of its volume.
Who's atomic theory stated that atoms have 3 fundamental parts and the electrons orbit the nucleus?
There were many scientists that worked on trying to prove that atoms exist. Neils Bohr was one of the first to discover that atoms had three parts and the electrons orbited the nucleus in 1913.
How does salt affect the movement of molecules?
Salt affect the movement of molecules due to its atoms and neurons and electrons contains it.
A substance that contains the element whose atoms have 12 electrons indicate which element?
Magnesium atoms have 12 electrons.
Does an electron contain many atoms?
A single electron contains no atoms; atoms contain electrons instead.
What are the major parts of atoms?
The nucleus,which contains electrons(-) and protons(+)
How are an atoms nucleus and its electron cloud different?
An atoms nucleus contains the proton and neutron while the electron cloud contains its electrons
Does sulfur contain electrons?
Yes. All matter on Earth contains atoms and thus electrons.
What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Arrange atoms from smallest to largest?
An atoms size is relative to the number of electrons an atom contains. Atoms with the least number of electrons are the smallest atoms. When atoms have the same number of electrons, the atom with the most protons will have the largest nuclear charge, and therefore be the smallest atom.
Which contains so little mass that it is insignificant Of the atoms three components?
electrons
What are the composition of atoms?
Speaking very generally, most atoms consist of a dense nucleus which contains protons and neutrons, and an electron cloud away from the nucleus which contains electrons.
Which would contain more electrons a mole of K atoms or a mole of Au atoms?
Let's see. 1 mole K atoms = 6.022 X 1023 atoms * 19 electrons = 1.144 X 1025 electrons in one mole potassium ------------------------------------------------------------- 1 mole Au atoms = 6.022 X 1023 atoms * 79 electrons = 4.757 X 1025 electrons in one mole gold ------------------------------------------------------ A mole of gold, Au, atoms contains more electrons than a mole of potassium, K, atoms.
What are in atoms?
Atoms are made of a nucleus, which contains subatomic particles called neutrons and protons, and electrons, which orbit the nucleus in certain areas.
What is proof that all atoms contains electron?
Definitions are enough to prove it. An atom is a combination of protons, neutrons and electrons with a balanced electrical charge. Thus all atoms contain electrons.
