What is the minimum number of electrons that would be expected to be in the valence shell of As in AsCL?
Arsenic (As) has five valence electrons, as it is located in group 15 of the Periodic Table. In AsCl, arsenic forms a covalent bond with chlorine (Cl), which has seven valence electrons. The minimum number of electrons in the valence shell of arsenic in this compound would still be five, as it does not lose any of its valence electrons despite forming bonds. Therefore, As would have five electrons in its valence shell in AsCl.

What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3A element is 3. These elements have three valence electrons because they are located in group 3A of the periodic table, which corresponds to the third column from the left.
What is the minimum amount of valence electrons an atom can have?
To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.

What is the maximum and minimum oxidation number of arsenic?
Arsenic is in group 15, it can lose 5 valence electrons or gain 3 valence electrons to achieve the octet. Its minimum oxidation state we can predict as being -3, and its maximum as +5
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 number of valence electrons for He?
Two valence electrons.
How can you find the number of valence electrons?
the number of valence electrons is the number group on the table its on
How do you find the number of non-valence electrons?
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
Which number tells you the number of valence electrons?
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
