Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
What else can I help you with?
An element in the activity series can replace any element in its group?
No, an element in the activity series can only replace another element if it is higher on the series. Elements higher on the series are more reactive and can displace those below in a single displacement reaction.
How do you count how many atoms of each element in a formula?
You count the little number next to the element and you count how many there are add them together and there you have it. But if you are balancing an equation than you must use those numbers but do not add them together
What do atoms with the same number of protons make?
a double molecule. If you have the same number of protons, it is obviously the same element. You would just have one more molecule of that element. It could make is something like: 02 or 03 Yes, but isn't there a scientific term for a double molecule? -there are bonds...covalent bonds. this is the chemical bond between the element. it can be a double bond, triple... there are also ionic bonds (but those are different). so in this case it would be a double covalent bond or a triple covalent bond.
The elements that make up a compound and the number of atoms of each element in a unit of the compound can be shown in a?
A molecular formula shows this information. In sulfuric acid, for example, the formula is H2SO4 as you'll learn to write it. There is hydrogen (H), sulfur (S) and oxygen (O) in it, and there are specifically 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen. You already guessed (and correctly!) that those numbers, the numerical subscripts, tell an investigator how many of those particular atoms are in the molecule of sulfuric acid.
Which statement correctly describes how an elementb differs a compound?
An element is a pure substance made up of only one type of atom, while a compound is a substance composed of two or more different types of atoms chemically combined in a fixed ratio. Elements cannot be broken down into simpler substances by chemical means, whereas compounds can be broken down into their constituent elements through chemical reactions.
How are atoms of one element differs from those of other element?
atomic number of an atom is its own characteristic property,ie.the number of protons or electrons in an atom,which distinguishes atoms from one another
What is the relationship between atoms and an elements?
An element is made by atoms. smallest part of element is atom.
In what way are atoms of one element different from atoms of other elements?
The number of electrons and neutrons may differ for atoms of the same element. However, what distinguishes atoms of one element from those of a different element is the number of protons in the atom's nucleus. All of the atoms of an element have the same number of protons, which is the single most important determiner of the properties of an element.
Who came up with this quote all atoms of a given element are identical but they differ from those of any other element?
This quote is attributed to British physicist and chemist John Dalton, who proposed the atomic theory of matter in the early 19th century. Dalton's theory stated that all atoms of a given element are identical and have specific characteristics that differentiate them from atoms of other elements.
what are the 4 points in Dalton's atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
What did Henry moseley discover about the atom?
He found that atoms of each element contain a unique positive charge in their nucleus. This discovery helped to solve the mystery of what makes the atoms of one element different from those of another: An atom's identity comes from the number of protons in its nucleus.
Are atoms that have the same number of protons but differ in the number of neutrons?
Those are called Isotopes.
How the arrangement of the atoms and molecules in a sugar crystal differ from those in a piece of plastic?
the atoms dissolve with the atoms and the molecules to lock the sugar and salt / lock in to make the crystals
Is it possible for atoms of the same element to have different chemical properties?
Atoms of the same element differ in the number of neutrons in their nuclei. All atoms of a given element have the same number of protons, of course. The number of protons in a nucleus determines which element the atom is. But the number of neutrons can vary, and these different "versions" of a given element are called isotopes of that element. See the related question, which is linked below.
What did the chemist Dalton do?
John Dalton published his atomic theory in 1803 where he gives 7 postulates on what he determined atoms where at that time. 1.) Matter is composed of extremely small particles call atoms. 2.) Atoms are indivisible and indestructible 3.) Atoms are a given element are identical in size, mass, and chemical properties. 4.) Atoms of a specific element are different from those of another element 5.) Different atoms combine in simple whole-number ratios to form compounds. 6.) In a chemical reaction, atoms are separated, combined, or rearranged.
Atoms of an element can have different numbers of protons?
No, they can't. Atoms (be careful of the difference between atoms and ions) can only have different numbers of neutrons, and those are called isotopes.
What is the molecules in sodium?
Sodium is a metal atomic element. So it has no molecules (or whatsoever) in it. It is build up (like all elements) with a nucleus in the center and electrons 'rotating' in shells around it. The numbers and measures of those shells and the electrons therein differ from element to element. There are about 100 elements.
