How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Which pair of elements is more likely to have simliar properties two elements in same group or two in the same period?
Two elements in the same group are more likely to have similar properties. This is because elements in the same group have the same number of valence electrons, which largely determines their chemical behavior and reactivity. In contrast, elements in the same period have different numbers of valence electrons and can exhibit a wider range of properties.
Which group has different number of valance electrons?
The groups in the periodic table that have different numbers of valence electrons are the main group elements (Groups 1, 2, and 13-18). For example, Group 1 elements have one valence electron, while Group 2 elements have two. Transition metals (Groups 3-12) also display variability in their valence electron counts due to their d-orbital involvement, leading to a wider range of oxidation states. Each group’s distinct number of valence electrons determines its chemical properties and reactivity.
Which group of elements can have varying numbers of valence electrons metals noble gases non-metals?
Transition metals
Are the numbers of neutrons the same for elements in the same column on the periodic table?
No. It is not the same. the number of valence electrons are same for the elements in the same column (group).
How do you predict an elements group?
they have same numbers of electrons.
Do elements in the same group have similar atomic numbers?
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
Why do group 13 elements have different properties than group 12 elements?
theres a difference in the number of valence electrons
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
What do elements within a group have a similar number of?
Elements within a group have a similar number of valence electrons. These electrons are responsible for the chemical properties of an element, which is why elements within the same group often have similar chemical behavior.
What is different about the group 18 elements?
Group 19 elements have 8 valence electrons (obey octet rule) and are hence stable.
Which pair of elements is more likely to have simliar properties two elements in same group or two in the same period?
Two elements in the same group are more likely to have similar properties. This is because elements in the same group have the same number of valence electrons, which largely determines their chemical behavior and reactivity. In contrast, elements in the same period have different numbers of valence electrons and can exhibit a wider range of properties.
Which group has different number of valance electrons?
The groups in the periodic table that have different numbers of valence electrons are the main group elements (Groups 1, 2, and 13-18). For example, Group 1 elements have one valence electron, while Group 2 elements have two. Transition metals (Groups 3-12) also display variability in their valence electron counts due to their d-orbital involvement, leading to a wider range of oxidation states. Each group’s distinct number of valence electrons determines its chemical properties and reactivity.
The group number on the periodic table corresponds to which characteristic of the elements of that group?
use your brain.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
