A scientist claims to have discovered an element with 30 protons in its nucleus. He determines it has 60 electrons. Why is his i
UNO [17]

The number of electrons in an atom of an element being always the same

as the number of protons in its nucleus is False.

<h3>What is an Electron?</h3>

This is a sub-atomic particle which is negatively charged and is usually

involved in chemical reactions.

Electropositive elements donates electrons while electronegative

elements accepts electrons during chemical reactions which is why the

number of proton and electron aren't always the same.

When ammonium nitrate is added to a suspension of magnesium hydroxide in water, the Mg(OH)2 dissolves. Write a net ionic equatio
Viefleur [7K]

Answer:

Net ionic: Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O

Explanation:

OH^{-} in Mg(OH)_{2} reacts with NH_{4}^{+} to form NH_{3} and H_{2}O.

Due to this acid-base reaction, Mg(OH)_{2} become soluble whenever NH_{4}NO_{3} is added to suspension of Mg(OH)_{2}.

In this reaction, NH_{4}NO_{3} acts as an acid and Mg(OH)_{2} acts as a base.

Molecular equation: Mg(OH)_{2}+2NH_{4}NO_{3}\rightarrow Mg(NO_{3})_{2}+2NH_{3}+2H_{2}O

Total ionic: Mg(OH)_{2}+2NH_{4}^{+}+2NO_{3}^{-}\rightarrow Mg^{2+}+2NO_{3}^{-}+2NH_{3}+2H_{2}O

Net ionic: Mg(OH)_{2}+2NH_{4}^{+}\rightarrow Mg^{2+}+2NH_{3}+2H_{2}O

barxatty [35]

Answer:

the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions.
