What else can I help you with?
Which choice has the element groups in the correct order from left to right on the periodic table?
Alkali metals, alkaline earth metals, transition metals
What is the lightest of the alkali metals?
Lithium, sodium, potassium, in order of lighter to heavier
What family is the element Rubidium in?
It is a metallic element in the alkali family
Which elements are unstable when combined with water?
Alkali metals like sodium, potassium, and lithium are highly unstable when combined with water, as they react violently to produce hydrogen gas and can cause explosions. Similarly, certain alkaline earth metals like calcium and magnesium can also react vigorously with water, though less explosively than alkali metals.
What charge does an ion of an alkali metal have?
Your Alkali Metals are those elements on the leftmost column of the periodic table (except for Hydrogen). Lithium (Li), Sodium (Na), Potassium (K), Rubidium, Cesium, Francium. You can remember them as those that form the Alkali bases, Sodium Hydroxide (NaOH), and Potassium Hydroxide (KOH) among others. In Pure Metallic form, they would have a neutral charge. However, they are frequently found in ionic form where they loose an electron to form a positive ion with a +1 charge. Li+ Na+ K+ etc.
What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases

How does sodium reach its desired state?
Sodium is an alkali metal. All alkali metals have 1 electron in the valence shell. This means that the "desired state" is to have a full valence shell configuration. So, in order for sodium and other alkali metals to reach this state, it has to LOSE one electron, making it a positive ion (cation).
What charge does an ion of an alkali metal have?
Your Alkali Metals are those elements on the leftmost column of the periodic table (except for Hydrogen). Lithium (Li), Sodium (Na), Potassium (K), Rubidium, Cesium, Francium. You can remember them as those that form the Alkali bases, Sodium Hydroxide (NaOH), and Potassium Hydroxide (KOH) among others. In Pure Metallic form, they would have a neutral charge. However, they are frequently found in ionic form where they loose an electron to form a positive ion with a +1 charge. Li+ Na+ K+ etc.
What happens to the electrons in the outer shell when the alkali metals react with other elements?
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
What kind of atom tends to loose one electron?
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
What is the group order of alkali metals by reaction?
Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive. Lithium, Sodium, Potassium, Rubidium, Caesium, Francium
Which list has the classes of elements in order from most reactive to least reactive?
The order of reactivity among classes of elements typically follows this pattern: alkali metals (most reactive), alkaline earth metals, transition metals, metalloids, nonmetals, and noble gases (least reactive). Alkali metals, such as lithium and sodium, readily lose electrons, making them highly reactive, especially with water. Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
