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 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 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 how many protons are in the nucleus of an atom of chlorine?
There are 17 protons in the nucleus of an atom of chlorine.
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
Is an atom as tiny as a bacterium?
Yes, an atom is much smaller than a bacterium. Atoms are the basic building blocks of matter and are about 100,000 times smaller than the smallest bacteria. Bacteria are complex living organisms made up of many atoms.
How many protons are in the nucleus of an atom of osmium?
An atom of osmium has 76 protons in its nucleus.
How big the nucleus is compared to an electron?
That depends on your definition of 'nucleus'. The nucleus or core of an atom is, obviously, smaller than the atom as a whole. But seeing as you placed this question in biology, a cellular nucleus is many billions of times the size of an atom.
How many protons are in the nucleus of an atom?
The number of protons in the nucleus of an atom is equal to the atomic number of the element.
How many nucleus does aluminum have?
One aluminum atom has one nucleus.
How many protons does the nucleus of a silicon atom contain?
The nucleus of a silicon atom contains 14 protons.
