No, the number of valence electrons in an atom is not equal to its effective nuclear charge (Zeff) value. Valence electrons are the electrons in the outermost energy level of an atom, while the Zeff value represents the net positive charge experienced by an electron in the outermost energy level.
What else can I help you with?
How can one determine the number of valence electrons from an electron configuration?
To determine the number of valence electrons from an electron configuration, look at the highest energy level (n value) of the electrons in the configuration. The number of electrons in this highest energy level is the number of valence electrons.
How do you figure out valence shell and valence electrons?
To determine the valence shell, look at the outermost energy level of an atom (the highest value for "n" in the electron configuration). The valence electrons are the electrons in the outermost energy level of an atom, which are involved in bonding and chemical reactions. Count the number of electrons in the outermost energy level to find the valence electrons.
Does the valence shell of electrons determine how one atom bonds to another atom to make a molecule?
No, valence electrons are the electrons in the outermost energy level of an atom. A molecule is the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
The chemical properties of an atom are determined by its atomic?
The chemical properties of an atom are determined by its atomic number, which corresponds to the number of protons in the atom's nucleus. The number of protons influences the atom's interactions with other atoms and its ability to form chemical bonds.
What makes a element balanced?
An element is considered balanced when it has an equal number of protons and electrons, which results in a neutral charge. This balance ensures the stability of the atom. Balancing the number of neutrons in an atom is also important for stability, but this doesn't affect the charge of the atom.

What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
What is the value of n for the valence shells of as?
The value of 'n' for the valence shells is the number of shells that specific atom has
What is the valence value of an element?
The valence value of an element is the number of electrons that an atom can gain, lose, or share in order to achieve a stable electron configuration. It determines the element's ability to form chemical bonds with other elements.
What element has two valence electons?
Here at Afuelscience.com we use this method...the number of valence electrons is the number of s and p electrons in the outermost shell (highest n). The number of valence electrons can also be determined by counting across the period, skipping the transition metals, until the element is reached. It is also the group number. If there is more than one atom, the number of valence electrons is the sum of all the atoms in the molecule or polyatomic ion. For ions, add the value of a negative charge and subtract the value of a positive charge. >> Example 1 How many valence electrons are in the following? # N # H2S # CO32- # NH4+ Solution: # Nitrogen is in group 5A. It has five valence electrons. # Hydrogen has one valence electron, and sulfur has six. The total for the molecule is 2(1) + 6 = 8. # Carbon has four valence electrons; oxygen has six; then two for the charge. 4 + 3(6) + 2 = 24. # Nitrogen has five valence electrons; hydrogen has one, minus one for the charge. 5 + 4(1) - 1 = 8.
How can you predict and element's group and period?
Group No = No.of valence electrons in the outer configuration period No = principle quantum No.(n)of the last shell of outer configuration Eg:carbon EC=1s2 2s2 2p2 No.of valence electrons=4, indicates G.No.is IV n=2, indicates period No. is 2 chlorine EC=3s2 3p5 valence electrons=7,so G.No. is VII n=3,so period No is 3

How can an absolute value be equal to itself?
If a number is zero or positive, then its absolute value is equal to the number.
Where Place value and face value of a number is always equal at?
place value and face value of a number are always equal at ones place.
What makes a element balanced?
