What is the difference between electronegativity and ionization energy

Chemistry

Katena32 [7]3 years ago

Answer:

These properties are basically the inverse of each other.

Explanation:

  • Electronegativity is the tendency of an atom to attract an electron and make it a part of its orbital.

        Ionization enthalpy, is the energy required to remove an electron from                        an atom.

  • More electronegative atoms have high ionization enthalpies If the energy required to remove an electron is less, i.e. the atom has more tendency to give electron, it would thus have less tendency to take electron.
  • Values and tendency of electronegativity in the periodic table: In general, the electronegativity of a non‐metal is  larger than that of metal. For the elements of one period the electronegativities increase from  left to right across the periodic table. For the elements of one main group the electronegativities  decrease from top to bottom across the periodic table. To the subgroup elements, there’s no  regular rule.
  • Values and tendency of ionization potential in the periodic table: The first ionization energy is the energy which is  required when a gaseous atom/ion loses an electron to form a gaseous +1 valence ion. The  energy which is required for a gaseous +1 valence ion to loose an electron to form a gaseous +2  valence ion, is called the second ionization energy of an element.  In general, the second ionization energy is higher than the first ionization energy of an element. The first ionization energies of the elements of one period increase from the left to the right  across the periodic table. According to the elements of main group, the first ionization energies  generally decreases from top to bottom across the periodic table.

Ionization energy is the reverse of electronegativity. Ionization energy tells you how easily or how attracted you are to your own electrons so how hard is for somebody to steal them so it's about how much you hold on to your electrons.

Electronegativity is a chemical property and it's about how much can I steal somebody else's electrons. They are like two sides of the same coin. Electronegativity is affected by both its atomic number (number of protons in the core of an atom) and how far the valence electrons (the outermost electrons) are from the core.

How many moles of a gas would occupy 11.4 L at 273K and 2.00 atm?
bagirrra123 [75]

Answer:

1.02mol

Explanation:

Using the general gas equation below;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question,

P = 2.0 atm

V = 11.4L

T = 273K

n = ?

Using PV = nRT

n = PV/RT

n = 2 × 11.4/ 0.0821 × 273

n = 22.8/22.41

n = 1.017

n = 1.02mol

What amount (moles) of compound is present in 1.00 g of each of the compounds in Exercise 54?
Anika [276]

Answer:

1. Caffeine, C₈H₁₀N₄O₂

Amount = 1.00/194 = 0.00515 moles

2. Ethanol, C₂H₅OH

Amount = 0.0217 moles

3. Dry Ice, CO₂

amount = 0.0227 moles

<em>Note: The question is incomplete. The compound are as follows:</em>

<em> 1. Caffeine, C₈H₁₀N₄O₂;</em>

<em>2. Ethanol, C₂H₅OH;</em>

<em>3. Dry Ice, CO₂</em>

Explanation:

Amount (moles) = mass in grams /molar mass in grams per mole

1. Caffeine, C₈H₁₀N₄O₂

molar mass of caffeine = 194 g/mol

Amount = 1.00 g/194 g/mol = 0.00515 moles

2. Ethanol, C₂H₅OH

molar mass of ethanol = 46 g/mol

Amount = 1.00 g/46 g/mol = 0.0217 moles

3. Dry Ice, CO₂

molar mass of dry ice = 44 g/mol

amount = 1.00 g/44 g/mol = 0.0227 moles

Which statememt describes gravity? Select three options
Fofino [41]

Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.
