Which of the following would contain the greatest number of atoms?
482317
Atomic wt of Al is 13,Cu is 29,Zn is 30 and Fe is 26.So less atomic wt,Al contains more number of atoms in 50gm
421869
Protons, Neutrons, and electrons

Atomic radius (or size) increases as you go down and to the left on the periodic table.  Therefore, out of these, the largest would be K.

oxygen, nitrogen, every fuckin mineral and more on the periodic table...take chemistry

Francium and cesium are about 0.5.\nFluorine is highest at 3.9-4.0 (by Pauling's estimate)

A more generic term for the components of an atom is "sub-atomic particles."  I think that's the answer you're looking for.

i think...\nthe atom is the smallest thing u will ever find, it doesnt divide into anything. so when you cut it up, or split it, it kind of explodes. so an atom bomb is alot of atoms exploding at the same time. funny how the smallest things in the world cause the biggest damage possible, huh?

The atomic number is the number of protons.

No because an atom is only a single element and thus such a "universe" would have no chemical composition except for the single atom it would have been made from

It´s 10. Neon. \nIt has two energy levels, filled with 2 and 8 electrons respectively.

Here are the rules as far as I know...\n\n1. The maximum capacity of each shell is given by 2n^2 (where n is the shell number starting from the innermost shell)\n2. The maximum capacity of the last shell, regardless of the atom, is 8.\n3. The maximum capacity of the penultimate shell (the second last shell) is not more than 18.

For C, that would normally be true.\n\nFor D, the answer is 1.2X10^24 atoms.\n\nFor E, helium atoms escaped through effusion.

Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom, gold atoms. Atoms are the smallest particle into which an element can be divided. The ancient Greek philosophers developed the concept of the atom, although they considered it the fundamental particle that could not be broken down. Since the work of Enrico Fermi and his colleagues, we now know that the atom is divisible, often releasing tremendous energies as in nuclear explosions or (in a controlled fashion in) thermonuclear power plants.\n\nSubatomic particles were discovered during the 1800s. For our purposes we will concentrate only on three of them. The proton is located in the center (or nucleus) of an atom, each atom has at least one proton. Protons have a charge of +1, and a mass of approximately 1 atomic mass unit (amu). Elements differ from each other in the number of protons they have, e.g. Hydrogen has 1 proton; Helium has 2.\n\nThe neutron also is located in the atomic nucleus (except in Hydrogen). The neutron has no charge, and a mass of slightly over 1 amu. Some scientists propose the neutron is made up of a proton and electron-like particle.\n\nThe electron is a very small particle located outside the nucleus. Because they move at speeds near the speed of light the precise location of electrons is hard to pin down. Electrons occupy orbitals, or areas where they have a high statistical probability of occurring. The charge on an electron is -1. Its mass is negligible (approximately 1800 electrons are needed to equal the mass of one proton).\n\nThe atomic number is the number of protons an atom has. It is characteristic and unique for each element. The atomic mass (also referred to as the atomic weight) is the number of protons and neutrons in an atom. Atoms of an element that have differing numbers of neutrons (but a constant atomic number) are termed isotopes. Isotopes can be used to determine the diet of ancient peoples by determining proportions of isotopes in mummified or fossilized human tissues. Biochemical pathways can be deciphered by using isotopic tracers. The age of fossils and artifacts can be determined by using radioactive isotopes, either directly on the fossil (if it is young enough) or on the rocks that surround the fossil 9for older fossils like dinosaurs). Isotopes are also the source of radiation used in medical diagnostic and treatment procedures.\n\nNote that each of these isotopes of hydrogen has only one proton. Isotopes differ from each other in the number of neutrons, not in the number of protons.

Other isotopes are stable. Examples of radioisotopes are Carbon-14 (symbol 14C), and deuterium (also known as Hydrogen-2; 2H). Stable isotopes are 12C and 1H.\n\nCarbon has three isotopes, of which carbon-12 and carbon-14 are the most well known.

A major research institution has recently announced the discovery of the heaviest element yet known to science. This new element has been tentatively named "Administratium." Administratium has 1 neutron, 12 assistant neutrons, 75 deputy neutrons, and 111 assistant deputy neutrons, giving it an atomic mass of 312.

heaviest element would be Ununoctium (118) or the one with the largest atomic number, but ununoctium only exists for a infinitesimally short time, like the many other heavy elements
