Answer:

Si dos átomos tienen el mismo "Z" pero diferente "A" se trata de Isótopos.

Explanation:

Cada elemento químico se caracteriza por el número de protones de su núcleo, que se denomina número atómico Z. Pero en el núcleo de cada elemento también es posible encontrar neutrones, cuyo número puede variar. La masa atómica (A) se obtiene sumando el número de protones y de neutrones de un núcleo determinado.

Un mismo elemento químico puede estar constituido por átomos diferentes, es decir, sus números atómicos son iguales, pero el número másico es distinto. Estos átomos se denominan isótopos del elemento. Si a un átomo se le añade un neutrón, se convierte en un isótopo de ese elemento químico. En otras palabras, se denomina isótopos a los átomos de un mismo elemento, cuyos núcleos tienen una cantidad diferente de neutrones.

Los isótopos de un elemento tienen las mismas propiedades químicas, pero difieren algo en sus propiedades físicas.

Entonces, <em><u>si dos átomos tienen el mismo "Z" pero diferente "A" se trata de Isótopos.</u></em>

10. Summarize the effect of hydrogen bonding on boiling point.
oksano4ka [1.4K]

Answer:

10. it increases the boiling point because it is a stone bond and will require much energy to break it.

11.So, to boil liquid water, all hydrogen bonds have to be broken and it requires a large amount of energy. This isn't the case in HF; all hydrogen bonds need not to be broken, and therefore a lesser amount of energy is required. So HF boils at a much lower temperature as compared to water even though F has high electronegativity but the force of attraction or the intermolecular is is weak
