How many times smaller is a millimeter compared to a decimeter?
It is 100 times smaller, because a decimeter is 10 times smaller than a meter and a milimeter is 1,000 times smaller than a meter. 10/1000=100
How many electrons are in the nucleus of an atom with an atomic number of 20?
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
Which is smaller a cation or neutral atom?
Anions are Bigger, Cations are smaller.anions are negatively charged species because they have gained an extra electron, which is negatively charged. The more electrons an atom has the more the outer electrons are shielded from the pull that the positive nucleus has on them, therefore when an atom gains an electron the nucleus can not pull in a strongly and the resulting radius, specifically ionic radius is larger.cations have lost an electron and therefore do not have as many electrons to shield the outer shell electrons from the attraction of the nucleus, the electron cloud is pulled closer and they are smaller.
What is Found in the nucleus of the atom?
Protons and Neutrons are the main fundamental particles but physicists and nuclear chemists also believe that there are many other minor particles eg neutrinos, quarks, muons, positrons to mention a few. Higgs-boson particles??
Which contributes more to an atom's mass electrons or protons?
The proton contributes more even though there are equal numbers of both electrons and protons. The mass of a proton is one thousand times greater than the mass of an electron. Thus, the proton contributes more.
How much bigger is an atom compared to its nucleus?
The atom is about 10,000 times as big as the nucleus.
Why atomic mass is concentrated on the center of the atom?
The atom is essentially made out of two main components: the nucleus and the electrons. The nucleus is in the centre of the atom whilst the electrons orbit it from a distance. The mass of the electrons is almost negligible, being almost 2000 times smaller than a proton, which is part of the nucleus. The nucleus, whilst having a minute mass, is still many times greater than the electrons. This is why the mass is concentrated in the centre on the nucleus.
How many meters is an atom meter?
The nucleus of the atom has a diameter of about meter, whereas the atomic diameter is about meter. This means that the nucleus has a diameter 10,000 times smaller than the atom. The nucleus of the atom has a diameter of about meter, whereas the atomic diameter is about meter. This means that the nucleus has a diameter 10,000 times smaller than the atom.
How many particles are there in the nucleus of an atom of mercury?
there are 80 protons in the nucleus of an atom of mercury
How many protons nucleus have?
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
How many times smaller than a human hair is an atom?
Atoms are more then a million times smaller then human hair. Hope that helps =3!!
How many neutrons are are in the nucleus of one atom of xenon?
There are 77 Neutrons in the nucleus of one atom of Xenon
What are two differences between the nucleus of an atom and the electrons of an atom?
The nucleus of an atom has a positive electrical charge, the electrons have a negative electrical charge, and the nucleus is thousands of times heavier than the electrons (the exact ratio of weight varies, because although there are always as many protons as electrons, in a neutral atom, the number of neutrons varies).
Do electons contribute to the size of atom?
The short answer is yes. The 'electron cloud' surrounding the nucleus of the specific atom essentially increases the atoms size by many many thousands of times.
How many nucleus does aluminum have?
One aluminum atom has one nucleus.
What is the name of the particles that circles the nucleus of an atom?
Electrons are the particles that circle the nucleus of an atom.
How many particles are in the nucleus of an atom of xenon?
There can be between 124 and 136 particles (neutrons and protons) in the nucleus of a xenon atom.
