Light shining on a strip of metal can dislodge electrons. Do you think this is more consistent with light being made up of waves
Naya [18.7K]

Answer:

The correct answer to the following question will be "Particles".

Explanation:

  • A particle seems to be a little component of something, it's little. When you're talking about a subatomic particle, that would be a structured user likely won't see because it's quite unbelievably thin, but it has a tiny mass as well as structural integrity. Such particles seem to be tinier than that of the particles or atoms.
  • Such that the light which shines on the bit of metal could dissipate electrons, the particles seem to be more compatible with the light.

Use the portion of the periodic table shown below to answer the questions.
Bingel [31]

The two elements that have the same properties as sodium are potassium  and rubidium .

<h3>What is periodic table?</h3>

The periodic table is an arrangement of the elements in order of increasing atomic number.

From the list, the two elements that have the same properties as sodium are potassium  and rubidium .

Proton has an atomic number of 20 and a mass number of 40. The number of electrons is the same as the number of protons. Given that the atomic number is the number of protons present, we have 20 electrons and 20 protons.

Number of neutrons = Mass number  - Number of protons

= 40 - 20 = 20 neutrons

Sodium hydride racts with excess water to produce
romanna [79]

Answer:

0.96g of sodium hydride

Explanation:

Equation of reaction:

NaH + H20 = NaOH + H2

Mass of hydrogen gas produced (m) = PVM/RT

P = 765torr - 28torr = 737torr = 737/760 = 0.97atm, V = 982mL = 982cm^3, M = 2g/mol, R = 82.057cm^3.atm/gmol.K, T = 28°C = 28 + 273K = 301K

m = (0.97×982×2)/(82.057×301) = 0.08g of hydrogen gas

From the equation of reaction

1 mole (24g) of sodium hydride produced 1 mole (2g) of hydrogen gas

0.08g of hydrogen gas would be produced by (24×0.08)/2 = 0.96g of sodium hydride

Compare the following sodium atoms in terms of their neutrons and mass numbers 24Na, 23Na​
olga_2 [115]

Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)

<h3>Further explanation </h3>

The elements in nature have several types of isotopes

Isotopes have the same number of protons and having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

  • ₁₁²³Na

number of atoms = 11

mass number = 23

number of neutrons=23-11=12

  • ₁₁²⁴Na

number of atoms = 11

mass number = 24

number of neutrons=24-11=13
