- Alkaline earth metals are the second group of the Periodic Table.
- They are shiny, silvery-white, and relatively reactive.
- Alkaline earth metals have two valence electrons in their outer shell and tend to form 2+ cations in chemical reactions.
What else can I help you with?
The three main groups of elements are?
The three main groups of elements are metals, nonmetals, and metalloids. Metals are typically solid, shiny, malleable, and good conductors of electricity. Nonmetals are generally dull, brittle, and poor conductors of electricity. Metalloids have properties that are intermediate between metals and nonmetals.
Which element is soft solid?
All the alkali metals; the three heavier alkaline earth elements, calcium, strontium, and barium; and the white allotrope of phosphorus are all considered soft solids at room temperature.
What 3 families contain no radioactive elements?
Oh, dude, let me break it down for you. So, the three families that contain no radioactive elements are the noble gases, the alkaline earth metals, and the alkali metals. It's like they're the cool kids who don't mess around with that radioactive drama. Just chillin' with their stable atomic structures, you know?
What is an element that has some characteristics of metals and non-metals?
Metalloids, such as silicon and arsenic, have properties that are intermediate between metals and non-metals. They can exhibit characteristics of both groups, such as semi-conducting properties and varying degrees of metallic and non-metallic behavior.
What are the reactive groups of fatty acids?
The reactive groups in fatty acids are the carboxylic acid group (-COOH) and the hydrocarbon chain. The carboxylic acid group is a site for chemical reactions, such as esterification or hydrogenation, while the hydrocarbon chain can undergo processes like oxidation or enzymatic modification.
What arethree alkaline-earth metals besides calcium?
Beryllium, magnesium and barium are three more alkaline earth metals.
What are three radioactive are?
They are Alkali metals, Alkaline Earth metals, and Carbon 16. ----
What are the three groups you see on the periodic table?
You can see the Alkaline Metals, Alkaline Earth Metals, Transition Metals, Other Metals (poor conducting metals), metaloids (characteristics of metals and non-metals combined), non-metals, noble gases, and unknown metals (like #112-118)The transition metals at the bottom of the periodic table are lanthanides and actinides.3 main ones are usually: Alkaline metals, Transition metals, and Non-metals...I hope this was useful!-Fuyuki
What three alkaline earth metals produce a magnetic field?
None of the alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) produce a magnetic field in their pure elemental form.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
What group are in the main group in the periodic table?
The three main element groups are alkali metals , alkaline earth metals and halogen family.
What element is an example of an alkaline earth metal?
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
What is a metallic element that starts with letter I?
Most elements are metals, including alkali metals, alkaline earth metals, transition metals, basic metals, and rare earth elements. There are three (3) Metallic elements that start with the letter "I". These metals are are Iron (Fe) and Iridium (Ir), transition metals, and; Indium (In), classified as an "other metal".
What are the three classes of group A elements?
The three classes of group A elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of electricity. Nonmetals are usually dull, brittle, and poor conductors of electricity. Metalloids have properties of both metals and nonmetals.
What are three alkaline metals?
Beryllium magnesium strantium calcium barium radium
What are three characteristics of iron metals?
smoking
