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.
What element has an atomic number lower than that of aluminum less valence electron than the the group 16 elements?
Nitrogen
Which element is a metalloid with 4 valence electrons?
Germanium (Ge) Atomic Number- 32 Atomic Mass-72.59
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.
The number of valence electrons increases with increase in what from the beginning to the end of period 2?
The number of valence electrons increases with increase in atomic number from the beginning to the end of period 2. The maximum number of valence electrons possible in any outermost shell is 8.
Does the valence electrons equal the number of protons?
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.

Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
How do you determine the valence electrons of aluminium?
In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
What is the difference between the atomic number of an element and the number of valence electrons?
Describe the reactivity of halogens
What is the difference between the atomic number of an element and number of valence electrons?
Describe the reactivity of halogens
What element has 6 valence electrons and 52 protons in the nucleus?
The element with 6 valence electrons and 52 protons in the nucleus is tellurium, which has the atomic number 52.
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)
What is the atomic number of another element with the same number of valence electrons as N and P?
As: Arsenic 33
What are the most reactive elements?
That would be the element with the highest atomic number but the lowest number of valence electrons.
