As you move from left to right across a row (or period) in the Periodic Table, the following things change: -- atomic size goes down -- electronegativity goes up -- electron affinity goes up See the Web Links and Related Questions links to the left of this answer for more details about why the trends occur and also some important exceptions to these trends.
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.
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.
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.
False. Physical properties within a group (vertical columns) in the periodic table are more alike than physical properties within a period (horizontal rows). This is because elements within a group have similar electron configurations, leading to similar chemical behavior.
A period in the periodic table refers to a horizontal row of elements that have the same number of electron shells. A group, on the other hand, refers to a vertical column of elements that have similar chemical properties due to having the same number of valence electrons. So, elements within the same period do not have similar properties, but elements within the same group do.
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.
Yes, properties within a group are more alike than properties within a period.

Yes, element properties change as you move across a period due to the increasing number of protons in the nucleus and the change in electron configuration. Within a group, elements have similar properties because they have the same number of valence electrons, which determine their reactivity.

They have similar chemical properties.

False. Physical properties within a group (vertical columns) in the periodic table are more alike than physical properties within a period (horizontal rows). This is because elements within a group have similar electron configurations, leading to similar chemical behavior.
They have different numbers of valance electrons...
All of the elements in any one period of the Periodic Table have the same number of valence electrons.
Yes, elements within the same period of the periodic table have the same number of electron shells, which determines their chemical properties. Elements in the same period also have the same number of energy levels and are influenced by similar trends in atomic radius and electronegativity due to the reactivity of their valence electrons.
Trends in the properties of elements in a group or period can be explained in terms of the periodicity of their electronic structure. Factors such as the number of electron shells, effective nuclear charge, and valence electron configuration play a key role in determining the physical and chemical properties of elements within the periodic table.
