Alpha particles, also called alpha ray or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a <u>helium-4 nucleus. </u>They are generally produced in the process of alpha decay, but may also be produced in other ways.
Composition: 2 protons, 2 neutrons
Mass: 6.644657230(82)×10−27 kg; 4.0015061...
Electric charge: +2 e
Symbol: α, α2+, He2+
Na: +1 (sodium)
S: -2 (sulfur)
=> Na2S
Answer:
They have all the same number of protons and electrons ( 6)
Explanation:
Carbon 12, Carbon 13 and Carbon 14 are all isotopes of Carbon.
The definition of an isotope is: They have the same number of protons (and electrons), but a different number of neutrons. Different isotopes of the same element have different masses.
Carbon 12 means an isotope with mass 12 u
it has 6 protons,(and 6 electrons) and 6 neutrons : 6 neutrons + 6 protons = 12
Carbon 13 is an isotope with mass 13 u
It has the same amount of protons ( and electrons) as Carbon 12, so 6 protons and 6 electrons
13 - 6 = 7 ⇒ Carbon 13 has 7 neutrons
Carbon 14 is an isotope with mass 14
it has the same of protons ( and electrons) as Carbon 12 and Carbon 13, so 6 protons and 6 electrons
14 - 6 = 8 ⇒ Carbon 14 has 8 neutrons
We can conclude that Carbon 12, Carbon 13 and Carbon 14 are 3 isotopes of Carbon. They all have the same number of protons (and electrons) = 6.
This means the isotopes will also have the same atomic number, because they are all isotopes of the same element.
