Pretty sure it's the valence electrons
The numbering arrangement of elements is called the atomic number. Atomic number determines the number of protons in an element's nucleus and defines its unique chemical properties.
Pretty sure it's the valence electrons
The group number of A elements in the AB numbering system tells you the number of valence electrons that element has. Elements in the same group have the same number of valence electrons, which determines their chemical properties.
The number of valence electrons. :) have a good day breh
Isotopes of an element have the same number of protons, which determines the element's chemical properties. The differing number of neutrons in isotopes does not significantly affect the element's chemical behavior.
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
Element S has similar properties to element T but has a lower atomic number.
The chemical properties of an element depend on its electron configuration, which is in turn determined by the number of protons. Isotopes of an element differ in the number of neutrons, which, being neutral, have not influence on chemical properties.
The number of protons in the nucleus, which determines the element's identity, has the greatest effect on an element's properties. The number of electrons determines its chemical behavior, while the arrangement of electrons in energy levels plays a role in its physical properties.
The properties of an element are more closely related to its atomic structure, specifically the number of protons, neutrons, and electrons it has. These properties include atomic mass, atomic number, chemical reactivity, and physical characteristics like melting and boiling points. The arrangement of electrons in the outermost shell also plays a significant role in determining an element's properties.
Group 3A is an old numbering system of the groups of the periodic table. Using the modern numbering system of the groups, you are referring to group 13. The element in group 13, period 6 is thallium (Tl).
You can identify an element by its atomic number, which is unique to each element. Elements are also distinguished by their physical and chemical properties, such as color, density, melting point, and reactivity. The arrangement of electrons in an element's atomic structure is another key factor in identifying elements.
