If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
What is common to every element in a period?
The energy sublevel (s, p, d ,f) is always the same.
Why is the atomic number included in the periodic table?
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
How many shells do the 4th period elements have?
Every element in the first period has only one orbit. This means that they can have only a duplet in their valence shell, which happens to be their only electronic shell. The elements included in the first period are Hydrogen and Helium.
Is symbol for an element always the first letter of its name?
Every element has a one or two (or three, if the element doesn't have an official name yet) letter symbol.
What element is the first element in the fourth period?
The first element in the fourth period of the periodic table is potassium (K).
The first element in a period is always an active?
The first element in a period is an alkali metal.
First element locate in period 3?
The first element in period three of the periodic table of chemical elements is sodium (Na).
What is the fourth element in the the fourth period?
The first element in the fourth period of the Periodic Table is potassium (K).
If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
What is the first element in a period called?
Hydrogen
What is the first element in the first period in the periodic table?
hydrogen
The first element in the fourth period?
Potassium
The atomic number of sodium the first element in Period 3 is 11 The atomic number of the second element in this period is?
it must be 12.
What is the same for every element in the same period?
The number of electrons in its valence shell
What is the first element is used in making fertilizer?
The first element in the fourth period, which is used in making fertilizer, is potassium.
What element is the first one in the 4 period?
Potassium (K)
