Answer:
The amount of kinetic energy an object has depends on its
Motion
Explanation:
Only kinetic energy increases when the velocity of an object increases.
Answer:
the raising atomic number
Explanation:
Elements are listed on the periodic table according to their atomic number.
Answer:
The solvent is Nitrogen and the solute is oxygen
Explanation:
Normally the solvent always contains higher amount of substance than the solute in a particular solution
Explanation:
Metals usually have stronger electron affinity than non-metals:
In the periodic table, the trend of electron affinity is that it increases from left to right across the period and decrease down the group.
False
Noble gas elements have a very large value for electron affinity:
Electron affinity is the change in energy of an atom when an electron is added. Noble gases already have a complete octet configuration hence there is no reason to accept any electrons. This makes their electron affinity value less than or equal to zero.
False
Negative anions have a larger ionic radius than the atomic radius of their neutral atom:
Neutral atoms that gain electron are referred to as anions. The extra electron increases the electron-electron repulsion which pushes the electrons further apart and finally increased radius.
