4 carbon electrons. Hope this helps have a nice day
Answer:
48 N
Explanation:
f=ma (from Newton's second law of motion)
Answer:
D.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons and as such the is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon that has a total number of ten (10) electrons.
Hence, contains the same number of electrons as an atom of neon.
Nuclear fusion is the combination of two nuclei to form a heavier nucleus. Colliding hydrogen atoms to produce helium is a form of nuclear fusion.
0.342 x ) photons are required to emit 1 joule of energy.
<h3>What is a photon?</h3>
A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.
We need to find the number of photons emitted per second.
So we have E = hc ÷ λ
= (6.6 x x 3 x m/s) ÷ 6.78 x nm
= 2.92 x Joules
Now number of photons per second = I / E (I = intensity)
= 1 x joule / sec ÷ 2.92 x joule
= 0.342 x
Hence, 0.342 x ) photons are required to emit 1 joule of energy.
