What determines an elements property?
Chemical properties of an element determine by the number of electron
Does the number of neutrons in the nucleus of an atom give it a unique chemical nature?
The number of protons is most important as this defines the atom's atomic number and it's place in the periodic table of elements. The number of neutrons only makes for isotopes of the atom. That means carbon, for example, can have 12 neutrons in its most common form but can also have 13 neutrons. Whether it has 12 or 13 does not matter - it is still carbon. It is carbon because it has 12 protons.
What is the propites of the elements?
Different elements all have very different properties. However, you can define an element as a substance with only one type of atom in (e.g. only sulphur atoms). If a substance has more than one type of atom in, then it is either a compound or a mixture, depending on whether the elements have bonded.
Explain why elements within a group have similar chemical properties?
Elements in the same group have similar electronic configurations. For example, all elements in Group 1 contain 1 unpaired electron located in an S orbital. It's the electronic configuration of atoms (and to a lesser degree, their size and charge) which dictate their chemical properties. Nuclear properties, on the other hand are dictated largely by the atoms size and number of protons and neutrons. Chemists, for the most part, aren't interested in these.
How are properties determined on the periodic table?
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.
What determines the properties of 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.
Are neutrons important in chemical reaction?
No, absolutely not. There are much smaller particles, first Electrons (which are part of reactions), Then Quarks that neutrons and protons are made of (and are part of reactions), and much, much smaller particles after that also are involved in chemical reactions.
What unique properties do chemical elements have?
Chemical elements possess unique properties determined by their atomic structure, including the number of protons, neutrons, and electrons. These properties, such as atomic mass, electronegativity, and ionization energy, dictate how elements interact with one another and form compounds. Additionally, each element has distinct physical characteristics, such as melting and boiling points, density, and state of matter at room temperature. Together, these traits define the behavior and reactivity of elements in various chemical contexts.
What is an isotope and how is it determined?
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. They are determined based on their atomic mass, which is the sum of protons and neutrons in the nucleus. Isotopes of an element have similar chemical properties but may have different physical properties, such as radioactive decay rates.
Why do all istopes of an element have the same chemical peoperties?
because chemical properties are determined by the nomber of electrons and protons and all isotops have the same number electrons and protons. they differ in the number of neutrons alone which doesnt affect chemical properties
Why do all isotopes of an element have the same cheimcal properties?
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.

Why isotopes of the same element are not considered different elements?
Isotopes of the same element have the same number of protons, which is what defines an element. The only difference between isotopes is the number of neutrons in the nucleus. Since isotopes of an element have the same chemical properties, they are not considered different elements.

What is the smallest portion of a substance that retains the properties of elements?
An element has distinct chemical properties that are created by the unique interaction of its protons, neutrons and electrons. The smallest unit that retains this is the atom.
Are there neutrons in man made elements?
All chemical elements (excepting the isotope 1H) contain neutrons.
