All of the others in the same row of the Periodic Table as sodium.
What else can I help you with?
What is used to order elements on the periodic table?
The elements are arranged in increasing ATOMIC NUMBER. NOTE ; NOT atomic mass. The atomic Number = Number of protons = the number of electrons in the neutral atom. NB A different number of protons is a different element.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
What does the period number tell you?
It tells you the number of cations in the outer energy level of the element's atomic mass
How is each element placed in the periodic table?
Elements are arranged into rows in order of increasing mass, so that elements with similar properties were in the same column. They are organized by type, such as nonmetals, metals, and metalloids, and solids, liquid, gas, or not found in nature.
Magnetic items must contain what elements?
Magnetic items must contain elements such as iron, nickel, or cobalt. These elements have unpaired electrons in their outer shells, allowing them to align their magnetic moments and exhibit magnetic properties.
Which other elements contain the same number of atomic shells as sodium written as the chemical symbols?
The elements of period 3 has same number of shells as sodium. These elements are Mg, Al , Si, P , S, Cl and Ar.
What element has the same number of atomic shells as sodium?
All of the elements in the same period (row) of the periodic table as sodium have this property.
Does mg have the same number of atomic shells as na?
No, magnesium (Mg) has 3 atomic shells while sodium (Na) has 2 atomic shells. The number of atomic shells is determined by the number of electron shells in an atom.
What characteristics must two elements share if they are in the same period?
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
The rows going across the periodic table is known as periods and contain elements with the same number of?
The rows going across the periodic table are known as periods and contain elements with the same number of electron shells.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
Which determine the chemical properties of an element?
the atomic masses and atomic numbers... group number and period number... valence electrons and number of shells... these all determine the chemical properties of elements...
What are elements of a group that has the same number of shells?
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
What characteristics is shared by elements in the same period?
Elements in the same period share the same number of electron shells, or energy levels. This means they have similar atomic sizes and exhibit similar chemical properties due to their outermost electron configuration.
How are elements are arranged on periodic table?
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
