Could Rutherford make any conclusions about electrons based on the result of experiment?
MatroZZZ [7]

Answer:

They are so small that they barely make up any of the mass of the atom, and they are so miniscule that during Rutherford 's Gold foil experiment ,they didn't even react with the alpha particles. They circle the nucleus on a ring. shown through Rutherford Atomic Model

Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many molecules of hydrogen gas
Zinaida [17]

Answer: Number of molecules of hydrogen gas 6.32\times 10^{32}

Explanation:

2Na+2H_2O\rightarrow 2NaOH+H_2

Number of moles of sodium =\frac{\text{mass of sodium}}{\text{molar mass of sodium}}=\frac{48.7 g}{23 g/mol}=2.11mol

According to reaction , 2 moles of sodium produces 1 mole of hydrogen gas , then 2.11 mol of sodium will= \frac{1}{2}\times 2.11 mol of hydrogen gas that is 1.05 moles of hydrogen gas.

Number of molecules = N_A(\text{Avogadro number})\times moles of substance

Moles of hydrogen gas formed = 1.05 moles

Number of molecules of hydrogen gas = N_A\times moles of hydrogen gas

Number of molecules of hydrogen gas =6.022\times 10^{23} mole^{-1}\times 1.05 mole=6.32\times 10^{32}

Consider these elements: N, Mg, O, F, Al. a. Write the electron configuration for each element. b. Arrange the elements in order
My name is Ann [436]

Answer:

N- 1s2 2s2 2p3

Mg- 1s2 2s2 2p6 3s2

O- 1s2 2s2 2p4

F- 1s2 2s2 2p5

Al-1s2 2s2 2p6 3s2 3p1

Explanation:

Order of decreasing atomic radius

Mg,Al, N,O,F

Order of increasing ionization energy

Mg,Al, N,O,F

Reason:

Atomic radius decreases with increase in nonmetallic character. Looking at the electronic configurations, as effective nuclear charge increases, the atom becomes smaller and the attractive force between the nucleus and the outermost electrons increases. Hence, the radius of the atom decreases and ionization energy increases. Note that the addition of more orbital electrons implies addition of more nuclear charge since the both must exactly balance for the atom to remain electrically neutral. The more the electrons in the outermost shell, the higher the first ionization energy.
