An atom with an electrical charge is a(n) ________. isotope. compound. water. ion.

1 answer:

8 0

To know the right answer,. let us define each of the following choices.

1. Isotope is a group of atoms that belong to same element but differ on their mass numbers. As written in the periodic table, each element has a specific value of atomic numbers which represent the number of protons in the atom. But they may differ when it comes to the number of neutrons in the nucleus.

2. Compound is a combination of at least two elements together that are bonded by intermolecular forces like ionic or covalent bonding, electrostatic forces and London dispersion forces.

3. Water is a compound made up of two hydrogen atoms and one oxygen atom.

4. Ions are atoms of elements that are not neutral because they readily accep ot gain electrons from other elements. So, they exist as cations (positively charge ions) or anions (negatively charge ions).

Basing on the descriptions of each choice, the answer to the description of atoms with an electrical charge is an ion.

Does the reaction of a main-group metal oxide in water produce an acidic solution or a basic solution? Write a balanced equation

Fynjy0 [20]

Answer: The main group metal produce a basic solution in water and the reaction is $MO+H_2O\rightarrow M(OH)_2$

Explanation:

Main group elements are the elements that are present in s-block and p-block.

The metals that are the main group elements are located in Group IA, Group II A and Group III A.

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

Acidic oxides are formed by the non-metals.
Basic oxides are formed by the metals.

When a metal oxide is reacted with water, it leads to the formation of a base.

The general formula of the oxide formed by Group II-A metals is 'MO'

The chemical equation for the reaction of metal oxide of Group II-A and water follows:

$MO+H_2O\rightarrow M(OH)_2$

Hence, the main group metal produce a basic solution in water and the reaction is $MO+H_2O\rightarrow M(OH)_2$
