what chemical properties of an atom are determined by its?

The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.

2. The number of protons in one atom of an element determines the atom's _, and the number of electrons determines the Charge of the element. ... It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the "identity" of an element as well as its location on the periodic table.

Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons.

What is a chemical property? A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

An element's chemical properties and many of its physical properties are determined by its valence electrons. Halogens can be solids, liquids, or gases at standard conditions. Whose element symbols are the closes to what chemists use today?

An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

Chemical Properties of Atoms. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics.

The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.

['The number of protons in the nucleus of the atom is equal to the atomic number (Z).', 'The number of electrons in a neutral atom is equal to the number of protons.', 'The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.']

These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.

Explanation: The number of outer shell electrons determines the group number of the element. The number of occupied principle quantum shells (energy levels) determines the period of the element. The proton number determines the element itself and its position.

Protons and neutrons make up the nucleus of the atom (the center), and the electrons circle around the neutrons and protons. What determines the vast majority of characteristics in an atom? The vast majority of an atom's properties are determined by the number of electrons (or protons) that an atom has.

We learned that physical properties are things like shininess, conduction of heat or electricity, melting point, and density. Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction.

These outer-shell electrons (called valence electrons) are important in determining the chemical properties of the elements. An element's chemical properties are determined by the way in which its atoms interact with other atoms.

Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
