K3PO is not an element. If it existed it would be a compound, the quantities of the elements that make it up don't work out right. It might be a charged radical ion. I don't know
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
I assume you mean pure Lead, and I'm here to tell you that Lead is an element in the periodic table. The fact that it is an element means that it is only 1 type of atom; Lead! The atomic symbol for Lead is Pb.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
Not at all. The little numbers after the element's chemical symbol show you how many atoms of that element the compound has. For example, CH4 is methane, C2H6 is ethane, which would have 8 atoms instead of methane's 5, C3H8 is propane with 11 atoms, as long as hydrocarbons are concerned. But there are compounds such as proteins with hundreds of atoms and there their arrangement in space makes a lot of difference for their chemical and physiological properties.
If you mean carbon-12, there are 6.022 x 1023 atoms in one mole. This is true of any element and any of its isotopes. Therefore, one mole of any element or a particular isotope is 6.022 x 1023 atoms.
The atomic number number of an element, and the magnitude of the positive electrical charge on a nucleus of the atoms of the element.
Isotopes are atoms of the same element but with a different number of neutrons.
In one oxygen atom, there is 1 atom of oxygen. The term "atom" refers to a single, indivisible unit of an element.
I think you mean what has the ... A pure isotope of an element.
This is the number of atoms of a given element.
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
I assume you mean pure Lead, and I'm here to tell you that Lead is an element in the periodic table. The fact that it is an element means that it is only 1 type of atom; Lead! The atomic symbol for Lead is Pb.
Assuming that you mean one molecule of epsom salts, the answer is:magnesium : 1 sulphur : 1 oxygen : 4.
this mean like of human body
Yttrium is the name of the chemical element that has exactly 39 protons in the nucleus of each of its atoms.
Did you mean, "What could be different about 2 or more atoms of the same element?" If you did, the answer is that they can have a different number of neutrons.
