WitrynaScreening of the nuclear charge by core electrons in atoms is _____. 1. A) less efficient than that by valence electrons 2. B) more efficient than that by valence electrons 3. C) essentially identical to that by valence electrons 4. D) responsible for a general decrease in atomic radius going down a group 5. E) both essentially identical to that by valence … WitrynaBoth sodium and magnesium have metallic bonding between atoms. Outer electrons become delocalised and float freely between the positive ions. The positive ions … filemaker pro 14 training

WitrynaMagnesium + hydrochloric acid → magnesium chloride + hydrogen. Mg(s) + 2HCl(aq) → MgCl 2 (aq) + H 2 (g) The more reactive the metal, the more rapid the reaction is. Witryna18 lut 2024 · I know that sodium is more metallic than Be or Al but my mind stuck on strontium. -Strontium is the member of the fifth period and has greater number of shielding electrons than sodium (due to greater number of shells). This suggests that strontium should be more likeable to lose electrons. -But sodium has half filled … Witryna3 kwi 2024 · Therefore, from the above argument we can clearly say that sodium is more metallic than aluminium as it will lose one electron readily hence owns metallic character and this is the required answer. Note: Remember that removal of electrons results in an increase in effective nuclear charge and consequently causes … groesbeck tax office
