Why do all atoms have a different number of protons?
Dear questioner,As an answer to your question I should mention there are atoms which have the same number of protons but are considered different. These atoms are called Isotopes. Isotopes of an element have the same number of protons but the number of Neutrons are not the same. Isotopes have the same chemical virtues but in the physical virtues related to mass they are a bit different.
What 5 things did john Dalton state?
1) all matter is composed of atoms 2) all atoms of the same element are identical 3) all atoms of different elements are different 4) atoms cannot be destroyed, subdivided, or created 5)Law of Multiple Proportions - In chemical reactions, atoms are combined, separated, or rearranged in simple whole number ratios
Compounds are made from different atoms of two or more?
Yes, also molecules are like compounds, but they can have 2 or more of the same atom.
What was John Dalton's theory of the atom?
John Dalton is considered as the father of chemistry because of his first model of an atom.They are as follow: 1. Every matter is made up of very small particles known as an atom which are indivisible.2. Atoms cannot be created nor destroyed by any chemical process i.e..., atoms are indestructible. 3. All atoms of same element are same i.e.., identical in shape, mass, chemical properties etc. 4. Atoms of different elements are different sizes, masses and chemical properties etc. 5. Atoms of 2 or more elements combine together in a to form compound atoms, which they do so in simple numerical ratios(1:1 etc).
What is a collection of atoms called?
A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
What is Dalton's four principles?
All elements are composed of atoms.All atoms of the same elementhave the same mass, and atomsof different elements have different masses.Compounds contain atoms of more than one element.In a particular compound, atoms of different elements aalways combine in the same way.
What type of molecules are formed when atoms of different elements combine?
A combination of two atoms of different elements results in a molecule. A combination of two atoms of the same exact element results in two atoms of the same element stuck together, not a molecule. There is no name for this that I know of. --------- 1. Two oxygen atoms: a molecule of oxygen - O2. Many gases has diatomic molecules. Ozone has three oxygen atoms in molecule. 2. Allotropes can be formed from many atoms: allotropes of carbon, sulfur, phosphorus.
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
What is created when chemicals reactions join atoms together?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
Atoms of different elements are what?
Atoms of different elements have no specific relationship but if they have same no of neutrons then they are isotones, if they have same mass no then they are isobars, atomic no of two elements can neither be same.
Are the atoms the same or different in hydrogen?
All hydrogen atoms are the same but they are different from the atoms of other elements.
Why zero group elements are mono atomic?
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
What are the four points of DaltonS theory?
The four points of Dalton's theory were: 1. All elements are composed of atoms. 2. All atoms of the same element have the same mass, and atom of different elements have different masses. 3. Compounds contain atoms of more than one element. 4. In a particular compound, atoms of different elements always combine in the same way.
Atoms combine chemically with each other to form what?
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
What is created when chemicals reactions jion atoms togethter?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
A difference in the atomic number of atoms means the atoms are of same or diffierent elements?
Different atomic numbers represent different elements.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
