What determines the properties of an element?

The property of an element that determines its chemical behaviour is: (b) valency of an element. – Actually, the chemical behaviour of an element is determined by its electronic configuration.

What determines the properties of an atom and element?

The number of protons in the nucleus determines which element an atom is, while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo.

What determines what element?

An element is defined by its number of protons. Varying the number of neutrons will change the isotope of an element and varying the number of electrons will create an ion, but changing the number of protons changes the identity of the element itself.

What property of an element is determined by the number of protons in its nucleus?

atomic number
The number of protons in the nucleus of an atom is its atomic number, which is unique to each element. The number of protons identifies an element and determines its chemical properties. The elements are arranged in order of increasing atomic number on the periodic table.

How does the number of electrons determine the properties of an element?

The number of electrons, in turn, determines the chemical properties of the atom. Electrons have a negative charge. Since the atom is electrically neutral, the number of electrons must equal the number of protons. The electrons arrange themselves in energy levels around the nucleus.

How do the properties of electrons influence the properties of elements?

The number of electrons in an atom’s outermost valence shell governs its chemical properties. Elements react to form a closed shell, corresponding to the electron configuration s2p6 . This tendency is called the octet rule, because the atoms have eight valence electrons.

How do neutrons determine the properties of an atom?

The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess. Together, the number of protons and the number of neutrons determine an element’s mass number.

What determines the number of protons?

The number of protons is determined by the atomic number which can be found on the periodic table. The electrons are always the same as the protons in a neutral atom.

How do protons and electrons determine the properties of an atom?

The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element.

What rule determines the number of electrons that are gained or lost?

octet rule: Atoms lose, gain, or share electrons in order to have a full valence shell of eight electrons. Hydrogen is an exception because it can hold a maximum of two electrons in its valence level.

How many protons and electrons are in a gold atom?

For example, hydrogen has an atomic number of 1. This means that an atom of hydrogen has one proton, and, if it’s neutral, one electron as well. Gold, on the other hand, has an atomic number of 79, which means that an atom of gold has 79 protons, and, if it’s neutral, 79 electrons as well.

How is the chemical identity of an element determined?

Only the chemical identity of an element is determined by the number of protons present in the nucleus. For an atom to remain electrically neutral the number of protons must equal the number of electrons.

What determines the chemical property of an element?

The chemical property of any element is mostly dependent on the number of electrons in its outermost shell. The number of electrons determine the valency of the element which determine the type of bonds it will form.

What determines the number of protons and electrons in an element?

The number of protons determines the number of electrons, which determines the properties that mostly define the element. If the numbers of protons and electrons differ, powerful electrostatic forces will cause it to gain or lose an electron and become neutral most of the time.
