Write the chemical symbols for three different atomic cations that all have 14 protons
yuradex [85]

The symbols for three different cations with 14 protons are Si²⁺, Si⁴⁺, and Si³⁺.

An element with 14 protons must be <em>silicon, S</em>i.

Its electron configuration is [Ne] 3s²3p², so it could lose up to four valence electrons.

The most likely cations are Si²⁺, Si⁴⁺, and Si³⁺ (or Si⁺).

zvonat [6]

Answer:

1) D; 2) B

Explanation:

1) <em>Conservation of atoms </em>

D is correct.

It has four atoms of H and two of O on each side of the reaction arrow.

A. <em>Wrong</em>. It has the same number of H and O on each side, but it has the <em>wrong product</em>. The reaction forms O₂ molecules, not O atoms.  

B. <em>Wrong</em>. Atoms are balanced, but the <em>products are incorrect</em>.

C. <em>Wrong</em>. Atoms are balanced, but the <em>reactants are incorrect</em>.

===============

2) <em>Chemical equations </em>

B is correct.

The atoms are balanced, and the equation shows the correct formulas of the molecules.

A. <em>Wrong</em>. Atoms are balanced, and the formulas are correct, but the equation is <em>not in its simplest form</em>. The coefficients are not in their lowest terms. We must divide every coefficient by six to get the correct equation: H₂ + Cl₂ ⟶ 2HCl.

C. <em>Wrong</em>. The <em>reactants are incorrect</em>, and the equation is <em>not in its lowest terms</em>.

D. <em>Wrong</em>. The <em>reactants are incorrect</em>.
