Among these element groups, which is least likely to form ions?: 7A 3A 1A 4A
natta225 [31]

The  element  group  which  is least  likely  to form ions  is 4A  group


 <u><em>explanation</em></u>

Element   of   group  4A   has   4  valence  electrons.  for example Carbon which has   [He] 2S2 2P2  electron configuration has 4 valence electrons.

Since 4A elements has 4 valence electrons ,  it means  that  their valence shell  is half  filled which is  relatively stable. <em>For  this reason 4A element readily  form  ions.</em>

1. Double-Replacement reactions

2. Decomposition  

3. Combustion

4. Syntesis

5. Single replacement

<h3>Further explanation</h3>

Given

Chemical equations

Required

Type of reaction

Solution

1. 2AgNO₃ + MgCl₂ ⇒ 2AgCl + Mg(NO₃)₂

Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant

2. 2KBr⇒2K +Br₂

Decomposition  

Single compound breaks down in to 2 or more products

3. C₃H₈ + 5O₂ ⇒ 4H₂O + 3CO₂

Combustion

Hydrocarbon and Oxygen reaction and form water and carbon dioxide

4. NaO + H₂O ⇒ NaOH

Syntesis

2 or more reactants combine to form a single product

5. Zn + CuCl₂ ⇒ZnCl₂ + Cu

Single replacement

One element replaces another element from a compound
