The formation of an ionic bond involves .
Further Explanation:
Chemical bond is termed as the attractive force that is present between various atoms, ions or molecules. The existence of different chemical compounds is a result of chemical bonds. These bonds can be formed by electron transfer or electron sharing. Protons and neutrons never participate in the bond formation.
Covalent bond
The mutual sharing of electrons between the bonded atoms results in the formation of covalent bonds. Covalent compounds are formed due to presence of these bonds. This type of bonding usually takes place between two or more non-metals.
Ionic bond
The interaction between a metal and a non-metal is defined as an ionic bond. It occurs via the formation of ions by the respective neutral atoms. Here the electrons are completely transferred from metals to non-metals. Metals form cations by the loss of electrons while non-metals form anions by the gain of electrons.
Ionic compounds exist as a result of ionic bonds are called ionic compounds. These compounds are hard solids, good conductors of heat and electricity, have high heat of fusion and high boiling and melting points.
Therefore the formation of ionic bond involves the transfer of electrons.

Answer:
False.
Explanation:
False. The speed of sound is greater in aluminum than in steel.
Answer:
True
Explanation:
Without enough nitrogen there is not enough nutrients for plants to make both aminoacids and many products of secondary metabolism
If not, was energy released (exothermic) or absorbed (endothermic) by the molecules during this physical change?
Answer:
Answer is C because in exothermic reactions, energy releases.
in Cellular respiration,
ATP+H20 (water) = ADP+ Pi + Energy
So celullar respiration is exothermic and releases energy
Answer:
yes it is
Explanation:
because what ever you mix in it it would explode and give a chemical reaction
NaCl + Al(OH)3
1, 1, 1,3
1, 3, 1,3
3, 1, 3, 1
1, 3, 3, 1
Answer:
3, 1, 3, 1 is a required answer.
Answer:
Periodicity is best defined as:the repeating nature of physical and chemical properties with increasing atomic number.
Explanation:
The elements present in nature or discovered so far are arranged in the form of a table known as periodic table. This creation of table was started with previous scientists like
i) Dobereiner's law of triads: according to it the atomic mass of middle element is average of atomic mass of side elements.
ii) Newland's law of octave: the properties of elements are repeated after seven elements.
iii) Mendleev's periodic table: it was a regular arrangement of by then discovered elements based on their atomic mass.
Now
We have periodic table known as long form or modern periodic table. This table is based on atomic number. According to it , there is periodicity in the physical and chemical properties of elements if they are arranged in certain groups and periods based on their atomic number.
b. polyatomic ion
c. multivalent ion
d. electron ion
Answer:
The correct answer is option b, that is, polyatomic ion.
Explanation:
A molecular ion also called polyatomic ion refers to a charged chemical species comprising two or more atoms bonded covalently with each other. The polyatomic ions comprise two or more non-metallic atoms. An example of a polyatomic ion is an ion of nitrate that comprises one atom of nitrogen and three atoms of oxygen. As the atoms in a polyatomic ion are bonded covalently, they are considered to possess a single charged unit.
