What properties can be predicted from the position of an element in the periodic table?

What properties can be predicted from the position of an element in the periodic table?

Some of the properties of the elements can be predicted given their location in the periodic table. For instance, the reactivity of atoms is associated with the number of electrons, and therefore, reactivity of some atoms can be predicted based on their location on the periodic table.

How can you predict the identity of an element?

The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.

How does the positions of elements in the periodic table help you to predict its chemical properties explain with an example?

Explanation: Elements in the same group have the electronic structures and fall below each other. All the elements in the same group have the same number of electrons in its last shell, hence, the behave in a similar chemical way because it is the outermost electrons that take part in chemical reactions.

How can you predict the chemical behavior of an element?

When atoms react, they tend to try and achieve a full outer energy level, either by losing outer electrons, by gaining extra electrons or by sharing electrons with another atom. This means it is possible to predict the behavior of an atom by examining its electron configuration.

What are 3 things you can predict about an element from its position on the periodic table?

Lupe Tanner, Ph. D. 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 an elements period?

If you are given with the atomic number of an element you can find it’s period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.

What determines the characteristics of an element?

Atomic Number and Mass Atoms of each element contain a characteristic number of protons and electrons. The number of protons determines an element’s atomic number and is used to distinguish one element from another.

What determines the use of elements?

Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element’s electronic configuration, and particularly by its outermost valence electrons. In addition, the total number of electron shells an atom determines which period it belongs to.

How can the position of elements on the periodic table be used to predict how they react with other elements?

Thus, the columns of the periodic table reflect the number of electrons found in each element’s valence shell, which in turn determines how the element will react.

What is the significance of the vertical columns of the periodic table what is the significance of the horizontal rows?

The vertical columns in the periodic table are called groups. Elements in the same group have similar chemical properties and similar reactivities. The horizontal rows in the periodic table are called periods. Elements in the same period have properties which gradually change as you go across the period.

How can we predict the properties of elements?

The Periodic Table can predict the properties of new elements, because it organizes the elements according to their atomic numbers. They hope that the two nuclei at the centre of these atoms will fuse and form a heavier nucleus. When these heavy elements form, they are usually highly unstable.
