If you are given the complete chemical symbol for an atom or ion then how can you determine the number of each kind of particle in the atom or ion?
The number of atoms in a given mass is related to the atomic mass of the element and Avogadro's number, 6.22x1023. If, for instance, we have 18grams of carbon, we divide 18 by the atomic mass of carbon, 12, to get the number of moles, 1.5 (18/12=1.5). Each mole contains 6.22x1023 atoms, so our sample has 1.5mol x 6.22x1023atoms/mole = 9.33x1023 carbon atoms.

What is the smallest particle in matter with unique chemical properties?
An atom is the smallest particle in matter with unique chemical properties. Each element is characterized by the number of protons in its nucleus, which determines its chemical behavior.
What parts of an atom determine its chemical properties?
The number and arrangement of electrons in the atom's electron cloud determine its chemical properties. Electrons are involved in chemical reactions as they interact with other atoms. The number of protons in the atom's nucleus also plays a role in determining its chemical properties by defining its atomic number and identity.
When particle in a atom is responsible for its chemical properties?
This is the number of protons.
How can one determine the oxidation number of an element in a chemical compound?
To determine the oxidation number of an element in a chemical compound, you need to follow these steps: Identify the element in the compound. Determine the common oxidation states for that element. Assign the oxidation number based on the compound's overall charge and known rules for assigning oxidation numbers. By following these steps, you can accurately determine the oxidation number of an element in a chemical compound.
What subatomic particle determines the chemical properties of the atom?
ELEMENT
Which number in a nuclear chemical symbol represents the charge of the particle?
The number in a nuclear chemical symbol represents the charge of the particle is the atomic number or the number of protons in the nucleus.
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.

The identity of a chemical element is given by the number protons.
What does the coieffecient in a chemical equation tell you?
The number of that type particle involved in the reaction.
Which subatomic particle is identified by this number?
Proton numbers equal the atomic number and is an identifier of a chemical element.
Which determine the chemical properties of an element?
the atomic masses and atomic numbers... group number and period number... valence electrons and number of shells... these all determine the chemical properties of elements...
