• D.

Z:20=1s2 2s2 2p6 3s2 3p6 4s2

A. Z:19=1s2 2s2 2p6 3s2 3p6
Explanation
The given configuration represents the electron arrangement of potassium (K). The atomic number of potassium is 19, which means it has 19 electrons. The configuration shows that the first energy level (1s) has 2 electrons, the second energy level (2s) has 2 electrons, the second energy level (2p) has 6 electrons, the third energy level (3s) has 2 electrons, and the third energy level (3p) has 6 electrons. This configuration follows the Aufbau principle and the Pauli exclusion principle, which states that electrons fill the lowest energy levels first and that each orbital can hold a maximum of 2 electrons with opposite spins.

### La configuración electrónica del Galio es  [en blanco]

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1
Explanation
The electronic configuration of an atom describes the arrangement of electrons in its energy levels or shells. The given electronic configuration for Gallium (Ga) is correct. It follows the pattern of filling up the energy levels in order of increasing energy. The first two electrons fill the 1s orbital, the next two fill the 2s orbital, the following six fill the 2p orbital, and so on. The last electron fills the 4p orbital, giving Gallium a total of 31 electrons.

### Según la configuración (1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p) determina cual es su símbolo

• A.

Sr

• B.

RB

• C.

Rb

• D.

Rb

D. Rb
Explanation
The given electron configuration (1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p) corresponds to the element rubidium (Rb) on the periodic table. Therefore, the correct symbol for this element is Rb.

• 6.

### Los metales de transición se encuentran ubicados del periodo 4 al 7 y en el grupo 3 al 12

• A.

• B.

Falso

Explanation
The statement is true because transition metals are located in periods 4 to 7 and groups 3 to 12 of the periodic table. These metals have partially filled d orbitals, which gives them unique properties such as variable oxidation states, formation of colored compounds, and catalytic activity.

Rate this question:

• 7.

### Los gases nobles son metales

• A.

• B.

Falso

B. Falso
Explanation
The correct answer is false. The statement "los gases nobles son metales" is incorrect. Gases nobles, also known as noble gases, are a group of elements in the periodic table that are characterized by their low reactivity and full outer electron shells. They are not metals, but rather nonmetals. These gases include helium, neon, argon, krypton, xenon, and radon.

### Cuales son las regiones de la tabla

• A.

S, d, p, f, k

• B.

F,p,s,d,o

• C.

S, d, p, f

• D.

D,p,fx,l

C. S, d, p, f
Explanation
The correct answer is "s, d, p, f". These letters represent the different electron orbitals in an atom. The s orbital can hold a maximum of 2 electrons, the p orbital can hold a maximum of 6 electrons, the d orbital can hold a maximum of 10 electrons, and the f orbital can hold a maximum of 14 electrons. These orbitals are arranged in energy levels or shells around the nucleus of an atom.
