Answer:
for the how to get a carrot to float you would need to make a hole in it and make it hollow
Explanation:
The atomic size trend in the periodic table is increasing from right to left and from top to bottom. Hence when comparing a chlorine atom and a sodium atom, it is seen that chlorine is seen on the far left side of the periodic table while sodium is seen on the far right side. This means sodium is thus greater in atomic size than a chlorine atom.
That is only the combustion of a hydrocarbon. Rust is a combustion reaction because oxygen is added.
Fe(s) + O2(g) => FeO2(s)
Answer:
Ionic or Electrovalent Bond.
Explanation:
its ionic bond because the Halogen atom (F) is getting bigger with electrons. This increases the size of the dipoles which cause van der waals dispersion forces. Hence resulting to increase in the strenght of the bond.
Explanation:
Ionization energies are always negative quantities – (False)
Energy required to remove an outermost electron from gaseous atom is known as ionization energy. As energy is always required in ionization, therefore, ionization energy is always a positive quantity.
The third ionization energy is the energy needed to ionize three electrons from a neutral atom. (Ture)
1st ionization energy is the energy required to knock out outermost electron from neutral gaseous atom.
2nd ionization energy is the energy required to knock out second electron from neutral gaseous atom.
3rd ionization energy is the energy required to knock out third electron from neutral gaseous atom.
Oxygen has a larger first ionization energy than fluorine. (False)
Ionization energy increases when we move from left to right in a period. Fluorine comes after oxygen in 2nd period of the periodic table, so as per the trend, ionization energy of the fluorine is larger than oxygen.
The second ionization energy of an atom is always greater than its first ionization energy. (True)
Second ionization energy is always greater than first because of increased nuclear attraction after removing one electron.
