The electron configuration of an element is 1s22s22p4. Describe what most likely happens when two atoms of this element move tow
castortr0y [3046]

Answer:

Cuando dos átomos se acercan entre sí, se genera un compuesto al compartir pares de electrones que cada uno de los átomos aporta, permitiéndoles alcanzar los 8 electrones de valencia (octeto) en su capa externa.

Explanation:

La configuración electrónica del elemento puede escribirse de la siguiente manera;

1s²2s²2p⁴

La configuración electrónica dada es equivalente a la del oxígeno, por lo tanto, tenemos;

El número de electrones en la capa de valencia = 2 + 4 = 6 electrones

Por consiguiente, cada átomo necesita 2 electrones para completar sus 8 electrones (octeto) en la capa externa.

Al acercarse los dos átomos, reaccionan y se combinan para formar un compuesto al compartir 4 electrones, 2 de cada átomo, de modo que cada átomo obtenga 2 electrones adicionales en su órbita externa en el nuevo compuesto y así se logre la configuración estable de octeto para cada uno de los átomos en el compuesto recién formado.

What is the net ionic equation of the reaction of mgso4 with sr(no3)2? express you answer as a chemical equation including phase
castortr0y [3046]
MgSO4 and Sr(NO3)2 are soluble, leading to the following ionic equation: Mg+2 + SO4-2 + Sr+2 + 2NO3-1 → Mg+2 + 2NO3-2 + SrSO4. Since SrSO4 is insoluble, we cancel out Mg and 2NO3 from both sides, resulting in the net ionic equation: SO4-2 + Sr+2 → SrSO4

Heavy nuclides with too few neutrons to be in the band of stability are most likely to decay by what mode?
Anarel [2989]

Answer:

Positron emission

Explanation:

In positron emission, a proton transforms into a neutron. This alteration results in a daughter nucleus with its mass number increased by 1, while the atomic number remains unchanged. The formation of a new neutron boosts the neutron count in the daughter nucleus, thus enhancing the N/P ratio.

Concurrently, a positron is emitted along with an anti-neutrino to ensure spin conservation.
