Definimos la radiactividad como el proceso mediante el cual un núcleo inestable pierde energia mediante emisiones (puede emitir fotones, neutrones, etc.)

Así, la característica princpial es que el elemento debe ser inestable.

-------------------------------------

Cuando tenemos un elemento inestable, lo que puede deberse a que el elemento tiene un núcleo muy grande, o a que el elemento por alguna razón tiene muchos neutrones, este elemento querrá de alguna manera volver a un estado más estable.

Usualmente, la inestabilidad se ve representada como un dado exceso de energía, entonces la forma en la que el átomo se estabiliza es liberando energía de alguna forma.

Esta energía puede ser liberada mediante una desintegración, donde el elemento original se convierte en otros elementos y en el proceso se liberan nucleones, o por emisiones de fotones característicos del elemento, o de otras diversas formas que dependerán del caso particular.

Concluyendo la idea, para que un elemento sea radiactivo (es decir, emite radiación) la característica  que este elemento debe tener es que debe ser inestable.

An airplane travels with a constant velocity of 210 m/s and in the upper atmosphere where the plane is traveling there is a wind
kolezko [41]

Answer:

hello your question is incomplete the options are missing

Determine the resultant velocity for the plane when it is travelling

i) To the east

ii) To the west

answer :i)  270 i

             ii)  -150 i

Explanation:

velocity of Airplane = 210 m/s

wind velocity = 60 m/s to the east

The resultant velocity for the plane when it is travelling  

let the velocity of the wind = V2

           velocity of the plane = v1

i) The resultant velocity for the plane when travelling to the east

Vr = V2 i  + V1 i

Vr= 60i + 210i  = 270i

ii) resultant velocity when the plane is travelling to the west

Vr = - V1 i + V2i

     = -210i  + 60 i = -150 i

How many moles of NO2 form when<br> 63.25 g N2O5 decompose?<br> 2N2O5→ 4NO2 + 0₂
GREYUIT [131]

Answer:

1.1713 moles

Explanation:

RFM of N2O5= (14*2)+(16*4)=108

Moles of N2O5= Mass/RFM= 63.25/108= 0.5856 moles

Mole ratio of N2O5:NO2 = 2:4

Therefore moles of NO2= 4/2*0.5856= 1.1713 moles
