How can elements properties be predicted?

How can elements properties be predicted?

Elemental properties are predictable by the element position on the periodic table. Electronegativity is the tendency of an element to attract electrons. The further right and up on the periodic table, the higher the elements electronegativity.

What determines the properties of a molecule?

Molecular substances are formed when two or more atoms join together by covalent bonds. The properties of molecular substances depend on intermolecular force, which is the force of attraction between atoms.

What properties of matter can be predicted by the periodic table?

An element’s position on the periodic table can be used to predict an element’s number of outer electrons. Within the periodic table there are trends of atomic size, electronegativity, reactivity of metals, reactivity of nonmetals, electron affinity, and ionization energy.

Are the properties of elements the same when they are contained in compounds?

Compounds have NEITHER the same chemical properties NOR the same physical properties as their constituent elements.

How can an element’s properties be predicted quizlet?

How do you predict an element’s properties? The properties of an element can be predicted from its location in the periodic table.

Which property Cannot be predicted for an element based on its location in the periodic table?

These arise from the number of protons (and electrons), which, again, is the basis for the arrangement of the periodic table. The chemical name of an element cannot be predicted from the periodic table.

How does molecular shape affect properties?

The molecular structure affects the molecular properties because the shape of of a molecule has a lot to do with the polarity of the compound. Polar compounds tend to dissolve in polar compounds, have higher boiling and higher melting points and form solids or liquids.

Why do different molecules have different properties?

The difference in the number of protons and neutrons in atoms account for many of the different properties of elements. The number and arrangement of electrons in an atom define the chemical characteristics of elements. One way to think of electrons is that they are the part of the atom that “shows”.

Which properties Cannot be predicted from the position of elements in the periodic table?

The chemical name of an element cannot be predicted from the periodic table. Chemical names are given to elements as they are discovered.

What can be predicted from its location in the periodic table?

The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.

How can you predict when atoms will combine to form a molecule?

READ ALSO:   What are the techniques of kabaddi?

Molecules can be made of atoms of the same element (an element) or they can be made from two or more atoms of different elements. The periodic table can be used to predict how atoms will combine into molecules.

Has unique properties that are different from the properties of the elements that composes them?

compoundA substance made from two or more elements. Has unique properties that are different from the properties of its individual elements. chemical bondAny of several attractive forces that serve to bind atoms together to form molecules.
