Overview of Cobalt
Atomic Number:27
Group: 9
Period: 4
Series: Transition Metals
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
Sulfur (S) is the representative element in period 4 with six valence electrons.
The group number 17 comprises of elements that has seven electrons in their own outer level.
The element Silicon (Si) is in the third Period on the Periodic Table. It is also the second element in Group 14(4) - The Carbon Family. It has 14 electrons in 3 shells, with 4 electrons in the outer shell.
The representative element in Period 4 with three valence electrons is aluminum. Aluminum is a metal that is commonly used in various industries due to its light weight and corrosion resistance.

the element copper
Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
it is the very common atom Carbon. --- The element could be carbon, if the four electrons are in the valence shell. However, if it is total of four electrons, then the element will be beryllium
Cobalt
The representative element in period 4 with 3 valence electrons is phosphorus.
The group number 17 comprises of elements that has seven electrons in their own outer level.
n
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
The number of electrons is not the key factor in determining an element, because ions can have more or fewer electrons. However, assuming an element that hasn't gained or lost any electrons, the element would be Copper.
The element Silicon (Si) is in the third Period on the Periodic Table. It is also the second element in Group 14(4) - The Carbon Family. It has 14 electrons in 3 shells, with 4 electrons in the outer shell.
