The answer would be that the Electrons get farther from the nucleus. As you go down a group, the Period is increasing, which means that each time a shell is being added on as such the valence electron are moving further away from the nucleus. It is therefore easier for the valence electron to be removed thus why less energy is needed to remove that electron, thus a decrease in ionization energy.
Answer:
1) Sound waves are stores as electrical signal in the digital recording.
2) the electrical signal of the digital recording is transcribed and sent to the voice coils.
3) the voice coil changes this electrical signal into varying magnetic fields.
4) The magnetic field pushes and pulls the diaphragm of the speakers.
5) the pushing and pulling of the diaphragm generates sound waves in the speaker.
Lavoisier is known as the “Father of Modern Chemistry” or the “Father of Chemistry”.
He is famous for isolating oxygen and establishing the law of conservation of mass.
Answer:
See below!
Explanation:
Chlorine is very electronegative, meaning that it will pull electrons, or negativity toward itself. When it pulls the negativity towards itself, the chlorine becomes partially negative and the carbon becomes partially positive. Because of this, the compound is polar.
Atomic mass is the same as the grams per mole. 2.98x10²² is 0.0495 mol (2.98e22 ÷ 6.02e23). If we have 4 g/0.0495 mol, that's 80.81 g/mol, so the atomic mass is 80.81 amu. Make sense?
