the outermost energy level! ( :
The number of electrons in an element determines its chemical properties and behavior. Specifically, it influences how an element will bond with other elements to form compounds and determines its reactivity.
Yes and no; the number of protons determine the valance number of electrons. The valence level of electrons and how full/empty it is largely determines an elements chemical behavior. I would say that valence electrons are the main determinant, but that is predetermined by protons.
Electrons.
The subatomic particle that determines an atom's chemical properties is the electron. Electrons are involved in chemical bonding between atoms, which determines the reactivity and behavior of elements. The number and arrangement of electrons in an atom's electron cloud dictate how it interacts with other atoms.
Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.
their boiling point and melting point.....etc.
The number and arrangement of electrons determine how elements react chemically. Elements strive to achieve a stable electron configuration, such as a full outer electron shell, through gaining, losing, or sharing electrons with other elements. This determines an element's reactivity and chemical behavior.
Elements in the periodic table have predictable chemical properties based on their position because they have the same number of valence electrons. This determines how they will react with other elements and molecules. The periodic table's structure helps scientists predict the behavior of elements based on their properties.
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
An element's chemical properties are primarily determined by the number of protons and electrons in its atoms. These properties include reactivity, bonding behavior, and physical characteristics. The arrangement of electrons in the outermost energy level (valence electrons) is also important in determining how an element will interact with other elements.
No, chemical properties of elements are primarily determined by the number of protons in the nucleus, which determines the element's atomic number and thus its placement on the periodic table. Neutrons play a role in determining an element's stability and isotopic composition but do not significantly impact its chemical behavior.
Elements in same column have same number of outermost electrons. It determines chemical properties.
