What is the more common name for group 7 metals?
The more common name for group 7 metals is the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form salts with metals.
Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
How does reactivity of elements change across the periodic table?
this is called periodicity, the chemical properties of elements as you go across a period. The reactivity would be very great at first, especially if you are only crossing main group elements, and then would become less reactive, then very reactive again, and then one group over they would be completely inert
What does group 6A elements have compared to group 2A?
Group 2A * Known as Alkaline earth elements * All are metals * Occur only in compounds * React with oxygen in the general formula EO (where O is oxygen and E is Group 2A element)
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
What is the more common name for group 7 metals?
The more common name for group 7 metals is the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form salts with metals.
Are Physical properties within a period are more alike than physical properties within a group?
No, physical properties within a group are more alike than physical properties within a period. This is because elements in the same group have similar electron configurations, leading to similar chemical and physical properties, while elements in the same period have different numbers of electron shells and therefore different properties.
Are properties within a group are more alike than properties within a period?
Yes, properties within a group are more alike than properties within a period. This is because elements in the same group have similar outer electron configurations, which leads to similar chemical behaviors. In contrast, elements in a period have increasing atomic numbers and varying electron configurations, leading to more differences in properties.
Is a physical properties within a period more alike than physical properties within a group?
Physical properties within a group are more alike than within a period. Elements within the same group have similar electronic configurations, leading to comparable chemical behaviors and physical properties. In contrast, elements in the same period have varying electronic configurations, resulting in a wider range of physical properties.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
In a group labeled as A, as atomic numbers increase across a period, the reactivity of elements generally decreases. This is because as you move from left to right across a period, the elements have more protons in the nucleus, which leads to stronger nuclear charge and less tendency to lose electrons and react with other elements.
What elements have more predictable properties main group elements or transition elements?
main group elements
Are period 1 elements more electronegative than period 2 elements?
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
List what group Tungsten is in?
Tungsten's group or family is metals. NOT metalloids!! It is a solid. More common elements in this group are Cobalt, Iron, and Sodium. and i swear this is true. (:
Which is negative oxidation state in 13 group elements?
The most common negative oxidation state in Group 13 elements is -3. This is particularly seen in compounds where these elements form three bonds with more electronegative species.
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
