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 is made when 2 atoms combine?
When two atoms combine, they can form a molecule or a compound, depending on the type of atoms involved. A molecule is formed when two atoms of the same element combine, while a compound is formed when atoms of different elements combine. This combination is achieved through chemical bonding.
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.
What type of molecules are formed when atoms of different elements combine?
When atoms of different elements combine, they form molecules known as compounds. In compounds, atoms are bonded together through chemical bonds, such as ionic or covalent bonds, to create a new substance with unique properties.
When elements combine to make a compound is it always in the same proportion?
No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
When two or more atoms from at least two different elements combine what is formed?
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
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.
Do atoms of different elements have the same number of protons?
no
What is the relationship between atoms elements and compounds?
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
When two atoms of the element oxygen combine to form a molecule of oxygen the result is not a compound Why?
When two atoms of the element oxygen combine to form a molecule of oxygen (O2), it is still considered a pure substance because both atoms are of the same element. A compound is formed when atoms of different elements bond together. In this case, O2 is a molecule of an element rather than a compound because it consists of two atoms of the same element bonded together.
