Number of Protons=Atomic Number. In a neutral atom (any atom listed in the Periodic Table), the number of protons equals the number of electrons. This is because a proton has a +1 charge and an electron has a -1 charge.
Example: Carbon has an atomic number of 6. A neutral carbon atom therefore has 6 protons and 6 electrons. Unrelated, but sort of more relevant, carbon has four valence electrons.
If the carbon was written like so: C+, then the carbon would have a positive 1 charge and would have one less electron than the neutral carbon. The number of protons would remain the same at 6, but the total number of electrons would be 5.

How can you determine the number of valence electrons for an element on the periodic table?
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

What type of properties do valence elcectrons determine for an element?
Valence electrons determine the reactivity of the element.

How can you determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
How can one determine the number of electrons in an element?
To determine the number of electrons in an element, you can look at the element's atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
How do you work out how many electrons are in an element?
You can determine the number of electrons in an element by looking at its atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and since atoms are neutral, this also corresponds to the number of electrons.
What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"

What number of an element can be used to determine the number of electrons in an atom?
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
How do you know how many unpaired electrons are in an element?
You can determine the number of unpaired electrons in an element by examining its electron configuration. Unpaired electrons are found in the outermost energy level, and you can count them by looking for half-filled or singly occupied orbitals in the notation of the element.
What do Valence Electrons determine?
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
