A sodium atom has the electron configuration of [ 2,8,1 ] before bonding with a chlorine atom which has the electron configuration of [ 2,8,7 ].

because sodium becomes a one plus ion ( +1 ), it must lose an electron to become stable therefore when bonded the electron configuration becomes [ 2,8 ] this is the same as the noble gas, Neon [ 2,8 ].

because chlorine becomes a minus one ion ( -1 ), it must gain an electron to become stable therefore when boded the electron configuration becomes [ 2,8,8 ] this is the same as the noble gas, Argon [ 2,8,8 ].

hope this helps :)

In general, what makes one kind of amino acid different from other amino acids?
Vinvika [58]
There is part of an amino acid molecule that is called the R group or side chain.  The side chain of the amino acid called glycine is a single hydrogen atom. The side chain is what differs from amino acid to amino acid.

Calculate the mole fraction of the total ions in an aqueous solution prepared by dissolving 0.400 moles of CaI2 in 850.0 g of wa
Evgesh-ka [11]

Answer:

0.00840

Explanation:

The computation of the mole fraction is as follow:

As we know that

Molar mass = Number of grams ÷ number of moles

Or

number of moles = Number of grams ÷ molar mass

Given that

Number of moles of CaI2 = 0.400

And, Molar mass of water = 18.0 g/mol

Now  Number of moles of water is

= 850.0 g ÷ 18.0 g/mol

= 47.22 mol

And, Total number of moles is

= 0.400 + 47.22

= 47.62

So, Molar fraction of CaI2 is

= 0.400 ÷ 47.62

= 0.00840

if you take a dried out white rose and place the stem in food coloring, will the rose turn the color you put the stem in
cricket20 [7]

Answer:

Yes, this is true. The reason is that the flower transpires and sucks the water in and distributes it as much as it can. You can also flip it upside down and hang it with petals down , allowing the liquid to enter the flower and then retaining color for longer periods of time and having more color.

If 6.02×1023 atoms of element Y have a mass of 28.09 g, what is the identity of Y?
Mazyrski [523]

Silicon is the element having a mass of 28.09 g

<u>Explanation</u>:

  • Silicon is the element having an atomic mass of 28.09 g / mol. So 28.09 g of silicon contains 6.023 \times 10^23 atoms. One mole of each element can produce one mole of compound.
  • The Atomic weight of an element can be determined by the number of protons and neutrons present in one atom of that element. So atomic weight expressed in grams always contain the same number of atoms( 6.023 \times10^23).
  • Avagadro number is the number of atoms of 1 mole of any gas at standard temperature and pressure. It has been determined that 6.023 \times 10^23 atoms of an element are equal to the average atomic mass of that element.
