Difference Between Chemical and Physical Properties • The properties of a substance are classified into its physical properties and chemical properties. • While physical properties can be observed and measured easily without altering the nature of the substance chemical properties are those that decide how the substance behaves in different circumstances and how it reacts with other substances.

Which subatomic particle identifies an atom as that of a particular element? Asker's rating. The number of protons determines the atom's atomic number (and thus element identity). The number of protons plus neturons determines atom's mass. The number of neutrons determines the isotope of an element for a given number of protons. The number of protons minus the number of electrons determines the ionic charge.

- As we learned in the previous section, an element’s location on the periodic table tells us how many valence electrons it has. Because the valence electrons determine the reactivity and chemical properties of an element, we can use the periodic table as a map to determine the general properties of any element.

How do protons determine the properties of an atom? The number of protons determines the number of electrons. This, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide positive charge to the atom. The number of protons also determines the identity of the element. Electrons have a negative charge. Since the atom has no charge, the number of electrons must equal the number of protons. The electrons arrange themselves in energy levels around the nucleus.

What is an Atom? The number of protons in an atom defines what element it is. For example, carbon atoms have six protons, hydrogen atoms have one and oxygen atoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons in an atom also determines the chemical behavior of the element.

Physical and Chemical Properties of Matter Chemical Properties and Changes. Chemical properties of matter describes its potential to undergo some chemical change or reaction by virtue of its composition. What elements, electrons, and bonding are present to give the potential for chemical change. It is quite difficult to define a chemical property without using the word change.

Chemical & Physical Properties: Definitions Physical properties are those that can be observed without changing the identity of the substance. The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

Physical and Chemical Properties of Matter All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity. Chemical properties can be measured only by changing a substance's chemical identity.

What property of an atom identifies it as a certain element? (What makes an element and element) (:? And atom is a specific element dependent on the number of protons it has, which is also its atomic number. An atom with 1 proton will always be Hydrogen, for example. Just look at a period table to see the name of an element for however many protons it has. Majestic Computing · 6 years ago.
