Why there are 14 element in lanthanide series?
because there are only 14 electrons in the f orbital
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
All elements on the periodic table are neutral because they have the ame number of electrons as what other particle?
protons
Which contains elements with simliar properties in the periodic table?
A group contains elements having similar properties because of the same number of valence electrons present in the atoms of those elements. So, of example if you take group one containing Lithium, Sodium, Potassium, etc, they all have similar properties because of having the same valency (+1) .
How many valence electrons do the nob gas element contain?
noble gases all contain 8 valence electrons because they are in column 8A on the periodic chart
On the periodic table which is the simplest and most stable element because it contains 2 protons and two electrons?
Helium (He) Atomic Number: 2
Why there are 14 element in lanthanide series?
because there are only 14 electrons in the f orbital
Why is fluorine in group 7 of the periodic table?
Because it meets the criteria of the group and row as told and predicted by Mendeleev. The simplest reason it is in group 7 is because it has 7 electrons in it's outer shell!
What is period vllla on the periodic table so chemically unreactive?
Group 8 contains the noble gasses. They are nonreactive because they have a completed shell of electrons. Other elements react to try to get an outer shell that contains 8 electrons, but the noble gasses already have that so they don't need to react.
What is a family on the periodic table?
A family is a column in a periodic table; all elements in a family have similar physical and chemical properties, because they have the same numbers of valence electrons (outer electrons).
How many valence electrons does Xenon have?
The number of Valence Electrons of Xenon is 8 because it is in the eighth group on the periodic table
Why is Palladium on the periodic table?
Because Palladium is an element (it cannot be broken down into other substances) and the periodic table is a table of all of the elements we know of.
How can copper be isoelectronic with hydrogen?
because on the periodic table they both have the same amount of electrons. 1
How many electrons in the outer shell of phosphorus are there?
5 because it is in group 5 on the periodic table
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
Why are nitrogen and phosphorus are both in group 5 in the periodic table?
Because they both have 5 electrons in their outer shell. This is the way that the elements in the periodic table were grouped.
How do elements in the same column on the periodic table have similar properties?
Because they have the same number of valence electrons.
