State the periodic law, and explain its relation to electron configuration. (Use Na and K in your explanation.)
mina [271]

Answer:

Explanation:

The period law state that when elements are listed in order of their atomic numbers, the elements fall into recurring groups, so that there is a recurrence of similar properties at regular intervals.

Na and K in the periodic table fall into the same group, this is because they both have one electrons in their outermost shell.

Na 11 -1s2 2s2 2p6 3s1

K 19 - 1s2 2s2 2p6 3s2 3p6 4s1

They share similar chemical and physical properties. Na and K are very reactive metals, they can loose/donate their outermost electron to non metals in other to attain stable octet state.

The form ionic compound when they react with non metals.

¿Qué elemento tiene el mismo número de órbitas que el Hidrógeno? ¿Por qué? ¿Tienen propiedades similares, por qué?
Aliun [14]

What element has the same number of orbits as Hydrogen? Why? Do they have similar properties, why?

Answer:

Helium

Explanation:

Helium has the same number of orbitals as hydrogen because they belong to the same period on the periodic table.

Periods are the horizontal arrangement of elements. Elements in the same period are known to have the same number of electronic shell or orbitals.

In period 1 where we have just Hydrogen and Helium, the number of orbitals is 1.

 

For properties of a specie, elements in the same group which are the vertical arrangement of elements have the same properties. Since both Hydrogen and helium are in different groups, their properties differ.
