Does the valence electrons equal the number of protons?
Rarely. The number of valence electrons of an element depends on it's position on the periodic table. Any given element can have between 1-8 valence electrons. The number of valence electrons increases left to right on the periodic table, while the number of protons, which determine the atomic mass and identity of an element, increase in general. Therefore the number of valence electrons can only equal the number of protons at the 8th element and below (neon).
The properties of an element are more closely related to its?
number of valence electrons
What is the atomic number of another element with the same number of valence electrons as N and P?
As: Arsenic 33
What element has 6 valence electrons in the 4th energy level?
This element is caesium (Cs), with the atomic number 56.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What is the maximum number of covalent bonds an element with atomic number 7 can make with an element with atomic number of 16?
It can make maximum 2 covalent bonds as element of atomic number 7 has 5 valence electrons while element having 16 atomic number have 6 valence electrons.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.

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.
The properties of an element are more closely related to its?
number of valence electrons
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 number of valence electrons?
Describe the reactivity of halogens
What is the difference between the atomic number of an element and the number of valence electrons?
Describe the reactivity of halogens
How many valence electrons would an element with an atomic number of 14 have?
Four electrons
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 can you predict an element from it's position in the periodic table?
how many electrons it has---how many valence electrons and how many levels of electrons. its Atomic Mass its atomic number
What are the most reactive elements?
That would be the element with the highest atomic number but the lowest number of valence electrons.
