Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.
Explanation :
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.
The equation for the given reaction is,
Thus, the chemical symbol for the element that results from this process is, argon (Ar).

The energy of a photon is
E=hf
Where
E = Energy
h = Planck's constant (6.62607004Ă—10â’34 J s)
f = frequency of photon.
So plug in the known values
E = 6.62607004Ă—10â’34 J s * 7.03 x 10^14 1/s
E = 4.65812724x10^-19 J
Since we only have 3 significant figures, the rounded result is
E = 4.66x10^-19 J</span>
Answer:
148 grams of relative atomic mass
Explanation:
magnesium atomic mass : 24
nitrogen : 14
oxygen : 16
24 × 1
14 × 1 × 2
16 × 3 × 2
24 + 28 + 80 = 148 grams
