Which type of compound is composed of negatively and positively charged atoms?
Ionic compounds are composed of negatively and positively charged atoms or groups of atoms. In these compounds, ions are formed by the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions. This creates a stable structure held together by electrostatic forces.
Are toxins positively charged?
Toxins can be both positively charged (cations) or negatively charged (anions) depending on their molecular structure and composition. The charge of a toxin can influence its interactions with biological systems and affect its toxicity.
Would the Lewis structure for a cation contain more electrons or fewer electrons?
It would have fewer electrons. A cation is a positively charged ion which means that there are fewer negatively charged electrons than positively charged protons.
Is solute molecule negatively charged in water?
Not necessarily. Solute molecules can be neutral, positively charged, or negatively charged in water. The charge of the solute molecule depends on its chemical structure and the presence of any functional groups that can interact with water molecules.
Which protein essential for chromatin formation is?
Histones are essential proteins for chromatin formation. They help in packaging DNA into the chromatin structure by wrapping around the DNA and organizing it into nucleosomes.
Once DNA has replicated it condenses when negatively charged phosphate groups interact with positively charged protein molecules known as?
Once DNA has replicated, it condenses when negatively charged phosphate groups interact with positively charged protein molecules known as histones. This interaction helps to package the DNA into a more compact structure, known as chromatin, which plays a role in regulating gene expression.
What are the negatively charged electrons attracted to?
Negatively charged electrons are attracted to positively charged protons in an atom's nucleus through the electromagnetic force. This attraction keeps the electrons in orbit around the nucleus, forming the structure of an atom.

What structure is composed of DNA and protein?
Chromatin is the structure composed of DNA and proteins found in the nucleus of a cell. It helps to package and organize the genetic material (DNA) in a compact and functional way.
Are toxins positively charged?
Toxins can be both positively charged (cations) or negatively charged (anions) depending on their molecular structure and composition. The charge of a toxin can influence its interactions with biological systems and affect its toxicity.
Would the Lewis structure for a cation contain more electrons or fewer electrons?
It would have fewer electrons. A cation is a positively charged ion which means that there are fewer negatively charged electrons than positively charged protons.
How many times does DNA wrap around a histone in chromatin structure?
In chromatin structure, DNA wraps around a histone protein about 1.65 times.
Positively and negatively charged ions bind through ionic bonds to form crystals?
That is correct. Positively charged ions (cations) are attracted to negatively charged ions (anions) through electrostatic forces, creating a stable crystal lattice structure. Ionic bonds are relatively strong but can be disrupted by solvents or extreme conditions.
What structual units make up ionic solids?
Ionic solids are made up of a repeating pattern of positively and negatively charged ions held together by electrostatic forces. These ions are arranged in a three-dimensional lattice structure. The ions are usually a metal cation (positively charged) and a nonmetal anion (negatively charged).
What is sulfate charge?
Sulfate has a charge of -2. This means that it has two more negatively charged electrons compared to the number of positively charged protons in its structure.
Why is DNA negatively charged and how does this property affect its function in biological processes?
DNA is negatively charged because of the phosphate groups in its structure. This negative charge allows DNA to interact with positively charged molecules, such as proteins, in biological processes like gene expression and replication. The attraction between the negatively charged DNA and positively charged molecules helps regulate these processes and ensures they occur correctly.
Is solute molecule negatively charged in water?
Not necessarily. Solute molecules can be neutral, positively charged, or negatively charged in water. The charge of the solute molecule depends on its chemical structure and the presence of any functional groups that can interact with water molecules.
