It depends on what kind of label it is and what kind of period it is.
they are alike because they have zeros and they are different because of the place value;hope you liked this answer
they are alike because they are different columns of digits and they are different because they have different. ddf
Depend ong what place value
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.
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.
Each (horizontal) row is called a '''period''', whereas each (vertical) column is called a group.
no. There is one element for each kind of atom.
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
they have the same energy levels
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.
