What year did Dalton say that Atoms of the same element exactly alike?
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
Does all atoms of a given element are alike in all respects?
No, not all atoms of a given element are alike in all respects. Isotopes are atoms of the same element that have different numbers of neutrons, leading to variations in atomic mass. This means isotopes of the same element may behave slightly differently in certain chemical reactions.
If all atoms in a sample of matter are alike that kind of matter is?
an element
Why are the atoms in an element exactly alike in some ways but may not be alike in other ways?
they all have same number of protons and electrons (in unionized form) but may have different number of neutrons.
Who said atoms of the same element are exactly a like?
The statement that atoms of the same element are exactly alike is attributed to John Dalton, who proposed the atomic theory in the early 19th century. Dalton's theory posited that all atoms of a given element are identical in mass and properties, which laid the foundation for modern chemistry. However, it is important to note that later discoveries, such as isotopes, revealed that atoms of the same element can differ in mass due to variations in the number of neutrons.
When all atoms in a substance are alike the substance is a?
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
What year did Dalton say that Atoms of the same element exactly alike?
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
What are substances in which all atoms are alike?
A substance in which all atoms are alike is an element.
The atoms of anyone specific element are always?
alike
Do All atoms of an element have to be exactly alike?
yes they do
Does all atoms of a given element are alike in all respects?
No, not all atoms of a given element are alike in all respects. Isotopes are atoms of the same element that have different numbers of neutrons, leading to variations in atomic mass. This means isotopes of the same element may behave slightly differently in certain chemical reactions.
Dalton's atomic theory stated that every element was made of atoms that could not be subdivided atoms of the same element are like and?
Dalton's atomic theory states that elements are composed of indivisible atoms and that all atoms of a given element are identical in mass and properties. Atoms of different elements have different masses and properties.
If all atoms in a sample of matter are alike that kind of matter is a?

Do atoms of the same element differ in chemical properties?
No. Atoms of the same element have the same chemical properties.
