Sodium has a larger first ionization energy than potassium BECAUSE its easier to remove a 4s electron than a 3s electron. Select whether each statement is true (T) or false (F) and whether the second statement is a correct explanation (CE) for the first statement.1 pointT, T, CET, FF, TT, TF, F

2. Sodium metal has a low electronegativity value BECAUSE sodium has a strong attraction for electrons. Select whether each statement is true (T) or false (F) and whether the second statement is a correct explanation (CE) for the first statement.1 pointT, T, CET, TF, FT, FF, T

Three statements about potassium and chlorine and their ions are listed.3The atomic radius of a potassium atom is greater than the atomic radius of a chlorineatom.1The first ionisation energy of potassium is greater than the first ionisation energy ofchlorine.2The ionic radius of a potassium ion is greater than the ionic radius of a chloride ion.3Which statements are correct?2 and 3D1 and 3C2 onlyB1 onlyA

The statements in the table below are all about the same chemical element E. There may be one statement that is false because it contradicts the other three statements. If you find a false statement, check the box next to it. Otherwise, check the "no false statements" box under the table.statement false?Atoms of E are among the smallest in E's Period. E is a good reducing agent. Atoms of E have two s valence electrons. Atoms of E are difficult to ionize. No false statements

Based on their location on the periodic table, which of the following properties will both potassium (K) and sodium (Na) share?A They are poor conductors of electricity.B They exist as inert gases at room temperature.C They are metals that are very reactive.D They are nonmetals that are not reactive.

The correct order of 2nd ionisation energy ?Mn > Cu > Ti > VLi > Na < KCr > Mn > V > TiSi > Mg > Na > Al
