Why is argon the last element in its period?
Argon is the last element in its period (period 3) because it fills the 3p sublevel, which can hold a maximum of six electrons. After argon, the next element, potassium, begins filling the 4s sublevel in the next period (period 4).
Which element in period 4 has the highest electronegativity?
The element in period 4 with the highest electronegativity is chlorine.
What element is in period 4 group 2A?
The element in period 4 group 2A is calcium (Ca).
What element is group 4 period 5?
The element in group 4 period 5 is Zirconium (Zr).
What metallic element in period 4 has 20 electrons?
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
Why is argon the last element in its period?

What is the characteristic of last element in each period of periodic table?
The last element in each period is a noble element. It is non-reactive.
Which element in period 4 has the highest electronegativity?
The element in period 4 with the highest electronegativity is chlorine.
If an element is the last element in its period what does this mean?
If an element is the last element in its period, it means that element has the highest atomic number and electron capacity in that period. It typically signifies a transition to the next period, where chemical properties may change due to different electron configurations.
What element is in period 4 group 2A?
The element in period 4 group 2A is calcium (Ca).
What Period 4 element is in the same group as F?
Br (Bromine) is a period 4 element in the same group as F.
What element is group 4 period 5?
The element in group 4 period 5 is Zirconium (Zr).
What metallic element in period 4 has 20 electrons?
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
What period on the table is scandium?
Scandium is found in period 4 on the periodic table. It has an atomic number of 21 and is classified as a transition metal.
What is the difference between period 4 and 5 on the periodic table?
Period 4 has elements filling the 4th energy level, while Period 5 has elements filling the 5th energy level. This means that Period 5 elements have an additional electron shell compared to Period 4 elements. Period 5 elements also exhibit trends such as increasing atomic size and metallic character compared to Period 4.
What is An element in group 4 and the third period?
The element in Group 4 and the third period is silicon (Si). Silicon is a metalloid that is widely used in electronic devices, such as computer chips, due to its semiconductor properties.
What element is Group 1 period 4?
element K, or potassium
