2 atoms:
one mole is 6.022 times 10 to the 23 atoms according to Avogadro's Number, there are 2 Hydrogens in water, H20, so therefore 2 times 6.022 times to 10 to the 23 is your answer. O which means that ever molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O)
Answer:
p=m/v
p equals density M equals mass and v = volume
For the noble gasses, you get D, but metals are basically everywhere in the periodic table...
Answer:
ZcH's electrons = 5-2 = +3.
ZcH for inner electrons = -5 - 0 = +5.
Explanation:
Boron 1s² 2s² 2p
As, 2s ⇒ 2.58.
2p ⇒ 2.42.
Electrons = +3.
Greater than 2 cm = 0.35
Slightly greater than +3 .
