How are the elements in the periodic table arranged from left to right and top to bottom based on what value?

1 answer:

5 0

Well, elements are arranged based on a number of factors.

Left to right, elements are arranged based on atomic number. The atomic numbers of the elements are increasing by 1 as you move from left to right.

Top to bottom is based on increasing atomic radius. As you move from top to bottom, each succeeding element in a group gets an additional electron shell, increasing the atomic radius as you move down.

He, ne , Ar - Noble gas elements have the highest ionization energy,
while francium (87) has the lowest ionization energy because it is so far from helium, in short atom near to helium has higher ionization energy and the atom who is far away from helium have low ionization energy.

El número de átomos de una molécula depende de la --- de los elementos ya que es la capacidad de la union de átomos ?

ss7ja [257]

Answer:

El número de átomos de una molécula depende de la "valencia" de los elementos, ya que es la capacidad de la unión de los átomos.

Explanation:

La valencia de un elemento se define como la medida de la capacidad de combinación de un elemento. Es la capacidad de combinación de un elemento con otros elementos para formar un compuesto químico o molécula.

Básicamente es el número de electrones de valencia que un elemento puede perder, ganar o compartir para formar enlaces químicos requeridos a partir de compuestos o moléculas.

¡¡¡Espero que esto ayude!!!

English Translation

The number of atoms of a molecule depends on the "valency" of the elements since it is the capacity of the union of atoms.

The valency of an element is defined as the measure of the combining ability of an element. It is the combining capacity of an element with other elements to form a chemical compound or molecule.

It is basically the number of valence electrons that an element can lose, gain or share in order to form chemical bonds required to from compounds or molecules.

Hope this Helps!!!
