How are alkali metals and noble gases similar?
They are grouped together because they all behave similarly (except with different ferocity) and together form Group 1 of the periodic table. They are all in fact very soft metals that can be cut with a knife and have relatively low melting temperatures.
What is common in alkali metals halogens and noble gases?
Answer: Halogens and Alkali metals are always seprated by a nobel gas as halogens belong to 17th group and Alakali Metals belong to 1st group. All have atleast 1 electron.
What are the similarities and differences between alkali metals and alkaline earth metals?
Alkaline earth metals are the elements in the group 2. Both have basic properties. When added to water, both can form solutions having higher pH values (>pH). The main difference between alkali and alkaline is that alkali metals have one valence electron whereas alkaline earth metals have two valence electrons.
What are the similarities and differences between the group 1 alkali metals and Group 17 halogens?
As alkali metals, the Group I elements are non-molecular solids (almost all of them are!). On the other hand, the Group 17 elements are molecular, with discrete molecular boundaries as gases, liquids, or solids. Metals are reducing, and non-metals are oxidizing, and hence the alkali metals form salts with the halogens.
How are alkali metals are different from noble gases?
The electronic configuration states that alkali metals are highly reactive with one valence electron while noble gases are non-reactive with a full valence band or no unpaired electrons (to attract other electrons for bond formation).
Where are the alkali metals and noble gases on the periodic table?
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
How are halogens and noble gases similar?
Answer and Explanation: The halogens and noble gases are alike because they are all non-metallic elements, with the exception of astatine, a radioactive element, and… See full answer below.
How do noble gases separate halogens and alkali metals?
Noble gases separate the highly electronegative halogens and the highly electropositive alkali metals. Halogens can form negatively charged ions by gaining an electron. Whereas alkali metals can form positively charged ions by losing an electron.
What are some similarities between the group 1 and group 2 elements?
Both the groups contain metals. group 1 is for alkali metals and group 2 is for alkaline earth metals. group 1 metals are monovalent while group 2 metals are divalent.
What are the similarities with alkali metals?
Alkali metals share many similar properties including: They are shiny, soft, metals. They are very reactive. They all have one valence electron in the outermost shell which they seek to lose in order to have a full outer shell.
What does group 1 and group 17 have in common?
What does group 1 and group 17 have in common? Reactivity of Group 1 Elements Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
How are alkali metals and halogens similar and different?
Alkali metals are soft and reactive metals. They react vigorously with water and become more reactive. And other hand halogens are reactive non metals.
