How the d-block group number relte to the number of outer s and d electrons?
The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.
Is fluorine a stable element?
Carbon is group 14 element and comes under p-block elements. It is because its last electrons fall into the p-subshell. Its electronic configuration is 1s22s22p2 . Transition elements are the elements of d-block.They are named so because their position in the periodic table lies between the s-block and p-block elements. They have their last electrons filled in the d-orbital.
Which elements are transition elements?
It may include lawrencium, actinium, lutetium, or lanthanum.The whole group is copernicium (No. 112), rutherfordium, roentgenium, molybdenum, niobium, palladium, vanadium, iridium, seaborgium, zirconium, titanium, ruthenium, meitnerium, technetium, darmstadtium, tantalum, manganese, platinum, mercury, rhodium, scandium, cadmium, chromium, osmium, hafnium, rhenium, bohrium, hassium, yttrium, cobalt, nickel, copper, iron, tungsten, silver, gold, and zinc.

What is s block element?
S block elements are elements that contain their outermost electron in the s shell. S block elements are further divided into 2 groups.
Why s block elements are colourless?
They are not colourless! They are grey. Elements in the s-block are all metals.
What groups of elements does the s-block contian?
Group 1 and group 2 elements are called s-block elements
S block elements densities?
Densities of s block elements are less than water. They float on water.
How many elements fit into each of the four blocks of the periodic table?
4: the s-block, the p-block, the d-block, and the f-block. there is an theoratical g-block but its not counted because its theoratical lol.
What is an element in the s block or p block of the periodic table?
The elements in Groups 1 and 2 are in the s block. The elements in Groups 13-18 are in the p block.
Why is the s-block called s-block?
The elements in the s-block have their last electrons in their electron configuration in the s-orbital.
What are in the s- and p-blocks of the table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
What groups comprise each block of elements in the periodic table?
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
What is the s block of elements?
ns1 or ns2
Are in the s and p blocks of periodic table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
What are in the s- and p-blocks of the periodic table?
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
