The molar mass of atom 2Al2O7Si2 would be calculated as follows: 2(Al) + 2(O) + 7(O) + 2(Si) = 2(26.98 g/mol) + 2(16.00 g/mol) + 7(16.00 g/mol) + 2(28.09 g/mol) = 404.14 g/mol.
An electron is much smaller in size than an atom. An atom consists of a nucleus (protons and neutrons) surrounded by electrons. The size of an electron is much smaller compared to the entire atom.
The nucleus of an atom only makes up a tiny fraction of the total volume of the atom, typically less than 1%. The majority of an atom’s volume is composed of the electron cloud surrounding the nucleus.
The mass an atom of technetium isotope 98 is 16,27.10e-23 g.
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
Ancient Greek philosophers such as Democritus and Leucippus did not have experimental evidence to support their theory of the atom. Their idea of the atom was purely philosophical and lacked experimental verification until much later.
This statement is not correct. An atom is made up of a nucleus (containing protons and neutrons) surrounded by electrons. Electrons are subatomic particles that are much smaller and have much less mass than the nucleus of an atom.
These numbers actually vary between atom to atom.
pretty much everything is larger than an atom.
In a normal atom there are 1 electron, but some are different.
The barium atom has a much bigger radius.
the volume of atom is much greater than that of nucleus
An electron is much smaller in size than an atom. An atom consists of a nucleus (protons and neutrons) surrounded by electrons. The size of an electron is much smaller compared to the entire atom.
No, since electrons are part of an atom, they are smaller -- much smaller. In fact, they weigh practically nothing.
an atom is about a trillion times smaller then a speck of dust.
There are four atoms - One Carbon atom and Three Oxygen atoms.
the nucleus of an atom has a positive charge equal to the number of protons in the atom.
it would be as big as you want depending how much of the atom there is
