What 'Manufacturing fossil fuel energy is much less efficient than manufacturing?
Manufacturing fossil fuel energy is much less efficient than manufacturing _____.
What energy makes up less than 1 percent of the world's commercial energy?
Nuclear energy.Nucular EnergyNuclear EnergyLess than 1 percent of the worlds commercial energy is supplied by the sun. Solar energy is an under-utilized source of energy.
What percentage of energy in the world comes from geothermal energy?
Geothermal energy currently contributes to less than 1% of the world's energy supply.
Which element is more reactive lithium or beryllium?
Lithium is more reactive than beryllium. This is because lithium has one electron in its outer shell, making it easier for it to lose this electron and form positive ions compared to beryllium, which has two electrons in its outer shell.
Why are the valence electrons of calcium in the 4s orbital not the 3d orbital?
Valence electrons occupy higher energy levels first before moving to lower energy levels, according to the aufbau principle. In calcium, the 4s orbital has lower energy than the 3d orbital, so valence electrons fill the 4s orbital first before the 3d orbital.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential
Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
Why boron has a lower first-ionization energy than beryllium?
Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.
Why is the ionisation energy of boron less than that of beryllium?
The ionization energy of boron is lower than that of beryllium because in boron, the electron being removed is farther from the nucleus, experiencing less of the nuclear charge, making it easier to remove. Additionally, boron's electron configuration involves removing an electron from a higher energy level, which requires less energy compared to removing an electron from a lower energy level in beryllium.
Why ismthe second ionisation energy greater than first for lithium?
The second ionization energy for lithium is greater than the first because removing the second electron requires breaking a stronger bond due to the higher effective nuclear charge after the first electron is removed. This leads to a greater energy input to remove the second electron compared to the first.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
What is meant by the first ionisation energy of nitrogen?
The first ionization energy of nitrogen is the energy required to remove one electron from a neutral nitrogen atom to form a positively charged nitrogen ion. It represents the strength of the bond between the electron and the nitrogen atom.
First ionisation energies of alkaline earth metals are higher than those of alkali metals?
Yes, they are.
Why does helium has a higher first ionization energy than argon?
The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus. In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.
Why sulfur has a lower ionisation energy than phosphorus?
Sulfur has a lower ionization energy than phosphorus because sulfur's valence electrons are in a higher energy level, making them easier to remove. Additionally, sulfur's smaller atomic size compared to phosphorus results in stronger nuclear attraction, requiring less energy to remove an electron.
Why does Ca have a higher ionization energy than Ga?
because it lower than Ba as you go down ionization energy increases
