Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)
→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.
→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.

Answer:
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions.
Answer:
The mass of sugar used is 427.5 grams.
Explanation:
The formula of common sugar is 
.
Its molar mass of molecule is 342 grams per mole.
The number of moles of sugar used is equal to '1.25'
(NOTE : <em>You can calculate molar mass by adding the mass of all the atoms present in the atom. </em>
<em>Mass of Oxygen (O) = 16 ; Total number of Oxygen atoms present = 11</em>
<em>Mass of Hydrogen (H) =1 ; Total number of Hydrogen Atoms present = 22</em>
<em>Mass of Carbon (C) = 12 ; Total number of Carbon atoms present = 12</em>
<em>Total mass of molecule = 12 × 12 + 1 × 22 + 16 × 11 = 342</em>)
Answer:
Dipole, less electronegativity, higher electronegativity
Explanation:
!!! Incomplete Question
When two atoms with different electronegativities are bonded together, a bond dipole exists.
A bond dipole is a partial charge assigned to bonded atoms due to difference in electron density, difference in electronegativity is a factor to this.
These are displayed with an arrow originating at the atom with the less electronegativity and pointing toward the atom with the higher electronegativity value
Answer:
Mass = 20 g
Explanation:
Given data:
Number of moles of He = 5 mol
Mass of He = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass = 4 g/mol
by putting values,
5 mol = Mass / 4 g/mol
Mass = 5 mol × 4 g/mol
Mass = 20 g
