Why do the elements in a group of the period table have similar properties?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
Which of the representative elements in period 4 has 3 valence electrons?
scandium
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
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).
Elements in the same are similar due to similarities in their number of valence electrons?
Families or _GROUPS_ of elements are similar due to similarities in their number of valence electrons.Answer:
How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
Why do the elements in a group of the period table have similar properties?
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
How does the number of valence electrons for elements across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
Do elements in the same group or period have similar properties?
Elements of same group have the same number of valence electrons and hence have similar properties.
How are the properties of elements in the same period related?
Elements in the same period have identical numbers of valence electrons or electrons in the outer energy level.
Which of the representative elements in period 4 has 3 valence electrons?
scandium
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
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 kind of elements have the same number of valence electrons?
Valence electrons are the electrons in the outer energy level. Each period shares many similar characteristics, one of which being the amount of electrons in the outer energy level. If you are unfamiliar, the Periods are the Vertical Columns, and Families are the Rows. I hope this helps you.
