Atomic Number definition: The number of protons within the nucleus of x atom.
Atomic Mass definition: The number of protons and/+ neutrons within the nucleus of x atom.
The given information states that the element has 8 protons and 8 neutrons in its nuclei with 8 electrons revolving around it. If the atomic number is 'the number of protons' and we have 8 given protons, our answer would be 8. If the atomic mass is protons + neutrons and we have 8 protons and neutrons, our answer for atomic mass would inevitably be 16.
Therefore
Atomic number: 8
Atomic mass: 16
Answer:
High amplitude is equivalent to loud sounds.
Explanation:
Larger the amplitude, the higher the energy. In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. This amplitude is perceived by our ears as loudness.
Explanation:
It is known that formula for the ionization energy of hydrogen atom is as follows.
E = 
or, n = 
The value of energy is given as 0.544 eV. Therefore, we will calculate the value of n as follows.
n =
= 
= 5
Thus, we can conclude that n equals to 5 for a hydrogen atom if 0.544 eV of energy can ionize it.
