The atomic number determines how atoms will react.Lithium and sodium both have the same relative atomic mass. The relative atomic mass determines how atoms will react.Lithium and sodium both have 1 electron on their outer shell. The number of electrons on the outer shell determines how atoms will react.Lithium and sodium both have 1 proton on their outer shell. The number of protons on the outer shell determines how atoms will react.I DON'T KNOWSUBMIT ANSWER

sodium is more reaction than lithium because

Which one of the following explains why lithium is less reactive than sodium?• The outer electron in sodium is closer to the nucleus and is shielded by fewer inner shells of electrons.• This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it harder for sodium to lose its outer electron compared to lithium.• The outer electron in lithium is closer to the nucleus and is shielded by fewer inner shells of electrons.• This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it harder for lithium to lose its outer electron compared to sodium.• The outer electron in lithium is further away from the nucleus and is shielded by more inner shells of electrons.• This means there is a weaker attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it easier for lithium to lose its outer electron compared to sodium.I DON'T KNOWSUBMIT ANSWER

. Which of the following provides the best explanation for the many chemical similarities between sodium and potassium? 1 pointBoth have atomic masses between 20 and 40 amu.The atomic numbers of the two elements differ by less than 10.Both are main group elements.Both are solid at room temperature and pressure.Both have an ns^1 electron configuration for their highest occupied energy level.

Lithium and iron will react with oxygen.Compare the reaction of lithium with oxygen and iron with oxygen.Lithium reacts quickly with oxygen, whereas iron reacts very slowly. This is because iron is a transition metal and lithium is an alkali metal. Transition metals are less reactive than alkali metals.Lithium reacts quickly with oxygen, whereas iron reacts very slowly. This is because lithium is a transition metal and iron is an alkali metal. Alkali metals are less reactive than transition metals.Iron reacts quickly with oxygen, whereas lithium reacts very slowly. This is because iron is a transition metal and lithium is an alkali metal. Transition metals are less reactive than alkali metals.Lithium and iron both react quickly with oxygen. Iron is a transition metal and lithium is an alkali metal. All metals react similarly with oxygen.I DON'T KNOWSUBMIT ANSWER

Sodium and chromium will react with water.Compare the reaction of sodium with water and chromium with water.Sodium and chromium both react quickly with water. Chromium is a transition metal and sodium is an alkali metal. All metals react similarly with water.Sodium reacts quickly with water, whereas chromium reacts very slowly. This is because sodium is a transition metal and chromium is an alkali metal. Alkali metals are less reactive than transition metals.Chromium reacts quickly with water, whereas sodium reacts very slowly. This is because chromium is a transition metal and sodium is an alkali metal. Transition metals are less reactive than alkali metals.Sodium reacts quickly with water, whereas chromium reacts very slowly. This is because chromium is a transition metal and sodium is an alkali metal. Transition metals are less reactive than alkali metals.
