Atoms are considered to be neutral with equal numbers of protons and neutrons. If an atom takes on extra electron(s) it becomes negativelly charged and is termed an ion or more specifically an anion to distinguishi it from positively charged ions.
What else can I help you with?
Can polar covalent molecules dissolve in water?
Yes, polar covalent molecules can dissolve in water because water is a polar solvent. The partial positive and negative charges on polar covalent molecules interact with the partial charges on water molecules through electrostatic forces, allowing them to be surrounded and dissolved in water.
Why are polar covalently bonded molecules soluble in water and non polar are not?
Water is a polar covalent molecule. The partial charges in the molecule attract other charges, ionic or more partial charges from other covalent molecules and dissolves them. Nonpolar bonded molecules have no partial charges and the water molecules will attract each other thus not attracting the nonpolar and does not dissolve them.
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
Do polar molecules have ionic bonds?
Polar molecules typically do not conduct electricity as well as ionic molecules. This is because charges in polar molecules due to unequal sharing of electrons are not as strong as the charges on ions
Why is HCl capable of being dissolved in water?
HCl is a polar covalent molecule, which means it has a positive and negative end. When HCl is added to water, the partial charges on the H and Cl atoms interact with the partial charges on the water molecules, allowing HCl to dissociate into H+ and Cl- ions. This interaction between the molecules enables HCl to dissolve in water.
Give one reason why water molecules are attracted o each other?
The H atoms with partial + charges attract O atoms with partial - charges on other water molecules.
Characteristics for polar and nonpolar molecues?
Polar molecules have separation of charges .ie. they have a partial positive and partial negative charges on molecule as in water . Non polar molecules e.g.methane has no separation of positive and negative charges as difference of electronegativity in C and H is very small .
Can polar covalent molecules dissolve in water?
Yes, polar covalent molecules can dissolve in water because water is a polar solvent. The partial positive and negative charges on polar covalent molecules interact with the partial charges on water molecules through electrostatic forces, allowing them to be surrounded and dissolved in water.
What does electronegativity allow water to do?
The higher electronegativity of oxygen allows water to carry partial charges (negative on oxygen, positive on hydrogen). These partial charges allow water to bind strongly with itself, and allows it to interact with polar molecules. The partial charge allows polar molecules to dissolve in water.
Why are polar covalently bonded molecules soluble in water and non polar are not?
Water is a polar covalent molecule. The partial charges in the molecule attract other charges, ionic or more partial charges from other covalent molecules and dissolves them. Nonpolar bonded molecules have no partial charges and the water molecules will attract each other thus not attracting the nonpolar and does not dissolve them.
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
Molecules that do not have oppositely charged ends are what molecules?
Molecules that do not have oppositely charged ends are nonpolar molecules.
Do polar molecules have ionic bonds?
Polar molecules typically do not conduct electricity as well as ionic molecules. This is because charges in polar molecules due to unequal sharing of electrons are not as strong as the charges on ions
Why is HCl capable of being dissolved in water?

When HCl is added to water, the partial charges on the H and Cl atoms interact with the partial charges on the water molecules, allowing HCl to dissociate into H+ and Cl- ions. This interaction between the molecules enables HCl to dissolve in water.
What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
Describes a molecule with opposite charges on opposite ends?
A molecule with opposite charges on opposite ends is called a polar molecule. This occurs when there is an unequal distribution of electrons, leading to regions of positive and negative charge. Water (H2O) is a common example of a polar molecule with oxygen carrying a partial negative charge and hydrogen carrying a partial positive charge.
What is the significant force that attracts water molecules polar molecules to each other?
The significant force that attracts water molecules to each other is hydrogen bonding. Water molecules are polar, with a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. These opposite charges create electrostatic attractions that result in the formation of hydrogen bonds between water molecules.
