Sound energy is produced by vibrating objects.
Example: when you speak you vibrate the air molecules in the air. If you where to speak in space no “sound” would be produced since there is nothing for the vibration of your voice to travel through.
Answer: Atoms with 11 protons, 10 neutrons and 11 electrons belong to the same element with 11 protons, 12 neutrons and 11 electrons.
Explanation:
Elements that contain same number of valence electrons belong to the same group. This is because they will have same reactivity (or properties) due to which they lie in the same group.
For example, element with 11 protons, 10 neutrons and 11 electrons is same as the element with 11 protons, 12 neutrons and 11 electrons.
Hence, both these atoms belong to the same element.
Thus, we can conclude that atoms with 11 protons, 10 neutrons and 11 electrons belong to the same element with 11 protons, 12 neutrons and 11 electrons.
Is that high school stuff or college?
<u>Electromagnet</u> - the strong magnetic field produced inside a solenoid can be used to magnetize a piece of magnetic material like soft iron when placed inside the coil. the magnet so formed is called electromagnet. the magnetic effect remains only till the current is flowing through the solenoid.
