Answer:

C) 4.24 x 10^{-12}

Explanation:

E = Δmc^{2}

Δm = 0.0284 x 1.66 x 10^{-27} kg = 4.714x10^{-29}kg

putting value in above equation

E = 4.714x10^{-29}kg x (3x10^{8})^{2} = 4.24 x 10^{-12}

Classify the following atom as excited, ground state, or not possible.<br><br> 1s^2 2s^2 2p^6 3p^1
Luda [366]
According to Pauli's exclusion principle, the energy levels of the subshells should be arranged in an increasing manner. The energy of each subshell can be computed. In the sequence, the given subshells are arranged in a correct order. 30p allows 6 electrons at maximum so this configuration is considered as ground state

Cuántos electrones de Valencia tiene Ga
Zinaida [17]
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p1

Primero realizas la configuración electrónica que es la que te puse allá arriba.

Después miras el nivel en que termina, puede ser 1, 2, 3, 4 etc.

Entonces como el último número de la configuración electrónica es 4, entonces ese es el nivel

Y los electrones de el último nivel son los de Valencia

4s2, 4p1 sumas 2+1 que son los electrones que se encuentran en el último nivel.

por eso hay 3 electrones de valencia.
