Is chemical reactions a physical or chemical properties?
ChemicalTo determine it, you must alter the identity of the substance. See the Related Questions link to the left of this answer: "What is the difference between a chemical and physical property?"PhysicalElements cannot be altered, without disrupting the physical structure of the atom, so the atomic structure between the protons, neutrons, and electrons are physical.Barney9So which one is it...? Chemical or physical?~Physical. Barney9's answer was a little confusing.. but overall, you can identify an element without disrupting the atomic structure of it's atoms.
What properties could be used to describe an atom of a specific element?
Atoms of different elements are built of different numbers of protons, neutrons and electrons. The most important property is the number of protons, or atomic number, as this defines the element. The number of electrons is equal to this. The number of neutrons can vary but should be given as it defines which isotope you have. Alternatively, you can express this information as the proton number (i.e. number of protons) and the mass number (protons + neutrons). This latter method is more usual, and the two numbers are often written in front of the element's symbol. The positioning of the numbers is important, with the mass number on top and the proton number below. The script editor won't let me show this, but you'll see it in any chemistry book.
What does not state a property of electricity?
It is a flow of protons
The atomic numbers refer to the?
the number of protons found in the nucleus of an atom
How are the isotopes of an element are alike and how are they different?
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Is numbers of protons chemical or a physical change?
The number of protons in a nucleus is a property of the atom, not a change.
What determines and Atom chemical property?
This is the number of protons.

What subatomic particles help us to identify an atoms chemical property?
Protons! :)
What represent the chemical symbols and numbers?
they represent the number of protons the element has and what is their charge
How do you know if two atoms are isotope?
They have the same number of protons and therefore the same chemical properties. But they have different numbers of neutrons and so the atomic masses are different and so are some physical properties.
How many protons and electrons and neutrons are in the Bohr model?
These numbers are different for each chemical element.
What is the number of atoms in elements?
well there is 2 ways physical and chemical. physical it means itll depend on its size chemical mean itll depend on its atomic weight (protons+neutrons)
What describes a substances ability to change into a new substance with different properties?
The chemical property of a substance relates to its ability to undergo a change. It transforms the substance into different substances.
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.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
What is the smallest unit of substances that keeps all of the physical and chemical properties of that substance?
The atom or smaller, the amount of protons like helium always has 2 protons no matter what.
