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>

Speed of Light Math Quiz (20 points)
Goryan [66]

The wavelength of light : 4.14 x 10⁻⁵ m

<h3>Further explanation </h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

The energy of the light = 4.8 x 10⁻²¹ J

The wavelength of light :

\tt E=h.\dfrac{c}{\lambda}\\\\\lambda=\dfrac{h.c}{E}\\\\\lambda=\dfrac{6.626.10^{-34}\times 3.10^8}{4.8.10^{-21}}\\\\\lambda=4.14.10^{-5}~m

Plz help..<br> How to name alcohols...
earnstyle [38]

Answer:

Alcohols are usually named by the first procedure and are designated by an -ol suffix, as in ethanol, CH3CH2OH (note that a locator number is unnecessary on a two-carbon chain). On longer chains the location of the hydroxyl group determines chain numbering. For example: (CH3)2C=CHCH(OH)CH3 is 4-methyl-3-penten-2-ol.10
