By the outermost shell of electrons
The elements that compose it and the arrangement of its atoms
yes.
they are determined by the outermost shell of electrons
The Russian chemist Dmitri Mendeleev.
Compounds of different elements can have different properties because their properties are determined by the arrangement and interactions of the atoms within the compound. The types and numbers of elements present in a compound will influence its physical and chemical properties.
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.
False. The properties of a compound are not just the sum of its constituent elements, but are instead determined by the way those elements are bonded together in the compound. This can result in unique chemical and physical properties that differ from the individual elements.
The properties of elements are determined by their atomic structure, including the number of protons, neutrons, and electrons. The arrangement of these particles within an atom influences an element's chemical and physical properties. Characteristics like reactivity, melting point, and conductivity are all tied to an element's atomic structure.
The properties of a compound are usually different from those of its individual elements because chemical bonds are formed between the elements, leading to new chemical and physical properties. These properties are determined by the arrangement of atoms in the compound, as well as the type of bonds that are formed.
For heavy artificially elements is difficult (or impossible) to determine properties because the are obtained in quantities of only few atoms; and these atoms are very unstable !
Properties of elements on the periodic table are determined by their atomic structure, specifically the number of protons, neutrons, and electrons they possess. These properties include atomic number, atomic mass, reactivity, conductivity, and others. The arrangement of elements into rows (periods) and columns (groups) on the periodic table is based on similarities in their properties.
Yes, elements have a wide range of properties due to differences in their atomic structure, which can include properties such as melting point, boiling point, density, and reactivity. These properties are determined by the arrangement of electrons in an atom and the interactions between atoms.
