Are beryllium atoms identical?
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
Which of Dalton's ideas about atomic theory have been applied to current atomic theory?
all matter is made up of units called atoms atoms can bond to and un-bond from each other all atoms of the same element are identical. atoms can form bonds during chemical reactions the basic unit of matter is an atom atoms will have identical atomic mass if they are the same element
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.
Did john Dalton believe that every atom of silver is identical to every other atom of silver?
yes atoms of any element are the same
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.
Are beryllium atoms identical?

An element that has the same chemical properties as the other atoms of that element but that has a different number of?
substance
Does atoms have the same properties as the element?
Atoms do have the same properties as long as stable form of its corresponding element is not a molecule. For example H1 (Hydrogen) which is a single atom has the same properties that of Hydrogen as it doesn't require to be in a molecular form to be stable. On the other hand O1 (Oxygen) doesn't have the same properties as Oxygen that we breathe as that Oxygen is actually O2 which is actually necessary for it to remain stable.
What was Dalton's four proposals or therories?
Elements are made of tiny particles called atomsAll atoms of a given element are identical (Proven wrong)The atoms of a given element are different from any other element (Not completely true)Atoms of one element can combine with atoms of another element to form chemical compounds
An element that has the same chemical properties as other atoms of that elementbut that has a different number of neutrons is?
isotope
What are atoms called which cannot be chemically broken down?
Elements are substances made of identical atoms which cannot be broken down to other substances. Matter is anything that occupies space and has mass.
What was Daltons theory based on?
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
What are the principle of Dalton's atomic theory?
1. All matters is composed of indivisible atoms. 2. All atoms of a given element are identical in mass and all other properties. 3. Different elements have different atoms. 4. Atoms are indestructible and retain their identities in chemical reactions. 5. Chemical reactions involved the combination, separation, and rearrangement of atoms.

What are five postulates of Dalton's atomic theory?
The five main points of John Dalton's atomic theory are as followed: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.Atoms of one element can combine with atoms of other elements to form 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 is the modification of John Dalton's atomic theory?
Daltons said All elements are made up of atomsAtomos are indivisible and indistructableAtoms of a given element are identical in mass and in all other propertiesA compound is formed when the atoms of two or more elements combine
