Electrons carry a negative electrical charge & produces a magnetic field as they move through space
Answer:
Explanation:
Galaxies are moving closer
Lol they’re not gonna be able to answer if they can’t watch the video
Question 1
Adding an electron has no effect on the mass number but it reduces the atomic number by 1.
So, 234 91 Protactinium plus 0 negative 1 electron results to Thorium234 and
<span>7 4 Beryllium plus 0 negative 1 electron will result to </span><span>Lithium7
</span>Adding a Helium particle increases the mass number of the daughter nuclei by 4 and the atomic number by 2.
So, <span>234 90 Thorium plus 4 2 Helium will results to </span><span>Uranium238 and
</span>222 86 Radon plus 4 2 Helium will result to <span>Radium226.
<span>Question 2
</span>The mass number is the sum of protons and neutrons. If an element has y protons and x neutrons, then its mass number will be (y+x).<span>
</span></span><span>88 38 Strontium. This element has a mass number of 88 and atomic number(number of protons) 38. Neutrons = 88 - 30 = 50.
Doing the same for the other elements we have;
</span>14 6 Carbon ⇒ Neutrons = 14 - 6 = 8
<span> 127 53 Iodine </span>⇒Neutrons = 127 - 53 = 74<span>
4. 39 19 Potassium </span>⇒ Neutrons = 39 - 19 = 20
Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).
