Correct Answer
PROTONS, PROTONExplanation
A proton is an atomic particle that carries a positive charge. It is found in the nucleus of an atom along with neutrons. Protons are essential for determining the atomic number and identity of an element. They play a crucial role in chemical reactions and the formation of chemical bonds.Rate this question:
- 6.
ATOM THAT CARRIES A NEGETIVE CHARGE
Correct Answer
ELECTRONS, ELECTRONExplanation
Electrons are the atoms that carry a negative charge. They are subatomic particles that orbit around the nucleus of an atom. Electrons are negatively charged because they have a fundamental property called charge, which can be either positive or negative. In an atom, the number of electrons is equal to the number of protons in order to maintain overall electrical neutrality. When an atom gains or loses electrons, it becomes an ion with a positive or negative charge, respectively. Therefore, electrons are the correct answer as they are the particles responsible for carrying a negative charge.Rate this question:
- 7.
ATOMS THAT CARRIES NO CHARGE
Correct Answer
NEUTRONS, NEUTRONExplanation
Neutrons are atoms that carry no charge. They are subatomic particles found in the nucleus of an atom along with protons. While protons have a positive charge and electrons have a negative charge, neutrons have no charge at all. They are crucial for stabilizing the nucleus and determining the isotope of an element. Neutrons play a vital role in nuclear reactions and are also used in various scientific and medical applications, such as in nuclear power plants and cancer treatment.Rate this question:

WHAT IS THE MASS WEIGHT OF AN ELECTRON
Correct Answer
0Explanation
The mass weight of an electron is 0. This is because electrons are considered to have negligible mass compared to other particles. They are much lighter than protons and neutrons, which make up the nucleus of an atom. Therefore, when calculating the total mass of an atom, the mass of electrons is usually not taken into account.Rate this question:

Correct Answer
THEY ARE CREATED WHEN ATOMS DONATE OR RECIEVE ELECTRONS, AN ATTRACTION BETWEEN POSITIVE AND NEGATIVE IONS, AN ATTRACTION BETWEEN POSITIVE AND NEGETIVE IONS, AN ATTRACTION BETWEEN 2 ATOMSExplanation
Ionic bonds are created when atoms donate or receive electrons, resulting in the formation of positive and negative ions. These ions are then attracted to each other due to their opposite charges, creating an ionic bond. This attraction can occur between positive and negative ions or between two atoms.Rate this question:
- 18.
TRUE OR FALSE:IONIC COMPOUND DISSOCIATE WHEN THEY DISSOLVE IN WATER
Correct Answer
TRUEExplanation
Ionic compounds dissociate when they dissolve in water because water molecules surround the ions and pull them apart, breaking the ionic bonds. This process is known as hydration. The positive ions (cations) are attracted to the negative oxygen atoms in water, while the negative ions (anions) are attracted to the positive hydrogen atoms in water. As a result, the ions become surrounded by water molecules and are able to move freely in the solution, leading to the dissociation of the ionic compound.Rate this question:
- 19.
HOW ARE ELECTROLYTES FORMED:
Correct Answer
Ionic compounds dissociate when they dissolve in water , WHEN IONIC BON DISSOCIATE IN WATERExplanation
When ionic compounds dissolve in water, they break apart into their individual ions. This process is known as dissociation. The water molecules surround and separate the ions, allowing them to move freely in the solution. These ions are what we refer to as electrolytes, as they can conduct electricity due to the presence of charged particles.Rate this question:
- 20.
IN ORDER FOR NA+ TO BE CREATED. SHOULD ELECTRONS LOOSE AN ATOM
Correct Answer
LOSE ATOM, YESExplanation
The given answer suggests that in order for Na+ (sodium ion) to be created, electrons need to be lost by an atom. This is because sodium has one valence electron in its outermost energy level, and in order to achieve a stable electron configuration, it tends to lose this electron and form a positive ion with a +1 charge. This process of losing electrons is known as ionization. Therefore, the statement "LOSE ATOM, YES" correctly explains the process of creating Na+ ions.Rate this question:
- 21.
HOW ARE COVALENT BONDS CREATED
Correct Answer
THEY ARE CREATED WHEN ATOMS SHARE ELECTRON, WHEN TWO ATOMS SHARE AN ELECTRONExplanation
Covalent bonds are formed when atoms share electrons. In this process, two atoms come together and each contribute one or more electrons to a shared electron pair. This sharing of electrons allows both atoms to achieve a more stable electron configuration, similar to that of a noble gas. The shared electrons are attracted to both nuclei, creating a strong bond between the atoms. This type of bond is typically found between nonmetals or between a nonmetal and a metalloid.Rate this question:
- 22.
