Answer:

The primary obstacle would be new experiments that go against the theory

Explanation:

Technology is advancing at an astonishing rate and society struggles to keep up. Over time, an increasing number of theories have been disproven, due to the limited resources available at the time they were suggested. Today, thanks to technological progress, theories can undergo practical testing and experimentation, leading to many being invalidated. Hence, a theory's greatest threat arises when it conflicts with contemporary evidence.

To identify factors that could undermine a scientific theory, one should consider "new experiments that oppose the theory." If an experiment were to disprove or challenge an aspect of the theory, this would represent the most significant challenge to it, necessitating further testing.

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.

From this list, choose all of the ionic compounds. Check all that apply. View Available Hint(s) Check all that apply. POCl3 KOCH
lions [2927]

Answer: KOCH_2CH_3, CH_3CH_2COONa, NaOH are all ionic compounds.

Explanation:

Ionic compounds form when one atom transfers its valence electrons to another atom, resulting in partial opposite charges on the participating atoms, which creates a strong attractive force between them.

An ionic bond is typically established between a metal and a non-metal.

For instance, KOCH_2CH_3, CH_3CH_2COONa, NaOH are all ionic compounds.

Conversely, a covalent compound arises through the sharing of electrons among the atoms involved, where generally a non-metal bonds with the same or another non-metal.

For example, POCl_{3}, SOCl_{2} etc are all covalent compounds.

Therefore, we can affirm that KOCH_2CH_3, [tex]CH_3CH_2COONa, NaOH are indeed ionic compounds.
