Which p-block element has 4 valence electron and is in the third period?
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.
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
How many valence electrons are there in an atom of gallium?
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
What is the non metal in the third period with six outer electrons?
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
Do Aluminum has the greatest number of valence electrons?
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.
Which p-block element has 4 valence electron and is in the third period?
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.
What can you predict about an element from its position in the period table?
how many electrons it has---how many valence electrons and how many levels of electrons. its atomic mass its atomic number
What element has 3 valence electrons and isn't a metal?
Boron
How many valence electrons are in calcium?
Calcium is a non metal element. There are 20 electrons in a single atom.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
What element has 6 valence electrons and 2 energy levels and is a non metal?
carbon
How many valence electrons are there in an atom of gallium?
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
Number of valence electrons in Lithium?
There is one valence electron in lithium, also in every other alkali metal element.
What is the non metal in the third period with six outer electrons?
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
Why do most element have a characteristics valence?
Valency depends upon no of electrons in outer most shell the atoms have a specific no of electrons in valence shell so they have characteristic valence .(but transition metal violate this rule).
Do Aluminum has the greatest number of valence electrons?
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.
