Any of the other alkali metals not mentioned (I.e. rubidium, caesium or francium). They are all group one metals meaning that they contain one valence (outer shell) electron so they will have similar properties. Francium is the most reactive alkali metal while lithium is the least reactive (if you’d like me to explain that let me know :) )
Double bonds are not formed by chlorine. To complete its octet, oxygen requires two bonds (two single bonds or one double bond) and two lone pairs.
Chlorine can only form single bonds unless, for instance, it is bonded to oxygen (ClO3H), in which case, the oxygen forces chlorine to form double bonds.
The chemical element chlorine has the atomic number 17 and the symbol Cl. The second-lightest halogen, fluorine is situated between bromine and fluorine in the periodic table and has most of its features in the middle. At room temperature, chlorine is a gas that is yellow-green.

To solve this, we need the Avogadros number to convert to
moles then multiply with molar mass to convert to mass in grams.
moles = 9.3 x 10^23 molecules * (1 mol / 6.022 x 10^23
molecules)
moles = 1.54 moles
Molar mass of NH3 is 17 g/mol:
mass = 1.54 moles * 17 g/mol
<span>mass = 26.25 g</span>
Answer:
The positive particles were deflected due the concentrated positive charge of the atom
Explanation:
Rutherford concluded that the positive particles were deflected through an angle greater than 90 due to electrostatic force of repulsion between the particles and positive part of the atom.
Answer:
Clarity and precision - these names are unique with each creature having only one scientific name. Helps avoid confusion created by common names. 3. Universal recognition - scientific names are standardised and accepted universally
Explanation:
