What element has an atomic number lower than that of aluminum less valence electron than the the group 16 elements?
Nitrogen
How many valence electrons are there is aluminum-25?
Number of valence electrons depends on number of electrons in uncharged atom(= atomic number), not on mass number. Al has atomic number = 13 and it belongs to group 13( III A) of periodic table so it's uncharged atom has 3 valence electrons. But valence electrons in ions is different. No. of valence electrons in an ion = No. of valence electrons in uncharged atom + negative charge or - positive charge1. 1. for charges only their magnitude is taken i.e. if charge is +2 or -2 then 2 is taken and put in equation.
This element has an atomic number lower than that of aluminum and one less valence election than the group 16 elements?
The element with an atomic number lower than aluminum is silicon, which has an atomic number of 14. Group 16 elements, like oxygen and sulfur, have 6 valence electrons, whereas silicon has 4 valence electrons.
How many electrons will be in the valence shell of an aluminum atom?
there are 3 valence electrons in the atom of aluminum
What does 3 refer to on an aluminium atom?
The +3 on aluminum refers to its oxidation number. The oxidation number of an atom is the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom. In this case, aluminum needs three valence electrons to form an octet (to have a total of eight valence electrons). If aluminum were to react with phosphate, PO4-3, the two would share their valence electrons and balance out, forming AlPO4.

How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Number of valence electron in aluminum?
Aluminum has 3 valence electrons
What is the atomic number and number of valence electrons for each nucleic acid elements?
For carbon (C): Atomic number 6, 4 valence electrons. For hydrogen (H): Atomic number 1, 1 valence electron. For nitrogen (N): Atomic number 7, 5 valence electrons. For oxygen (O): Atomic number 8, 6 valence electrons. For phosphorus (P): Atomic number 15, 5 valence electrons.

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.
What are the number of outer-shell electrons in one atom of aluminum?
Aluminum has 3 valence electrons.
