Whiat covalently connects segments of DNA?
Ligase covalently connects segments of DNA. It catalyses the joining of two large molecules by forming a new chemical bond.
Are elements are capable of forming compounds?
Yes, elements are capable of forming compounds by bonding together through chemical reactions to create molecules with different properties than the individual elements. These compounds can have unique characteristics, such as new chemical and physical properties.
What type of molecules is helium likely to form?
Helium is a noble gas and is unlikely to form molecules because it already has a full outer electron shell, making it very stable. Helium typically exists as single atoms rather than forming molecules with other elements.
What two elements make up most of the oceans?
The two elements that make up most of the oceans are hydrogen and oxygen, forming water molecules.
The most electronegative atoms typically present in biological molecules?
The most electronegative atoms typically present in biological molecules are oxygen (O) and nitrogen (N). These elements are often involved in forming polar bonds with hydrogen (H) atoms, contributing to the overall structure and function of biomolecules.
Hydrogen bonds are formed between molecules when hydrogen is covalently bonded to an element that has a?
high electronegativity, such as nitrogen, oxygen, or fluorine. This results in a partial positive charge on the hydrogen atom, which can attract a partial negative charge on another molecule containing those electronegative elements, forming a hydrogen bond.
Which 6 elements are the most predominant in forming biological molecules?
The six most predominant elements in biological molecules are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are essential for building the basic structure of biological molecules like proteins, nucleic acids, lipids, and carbohydrates.
What are low z-elements?
Low Z-elements, or low atomic number elements, refer to chemical elements with relatively low atomic numbers, typically those with atomic numbers less than 20. These elements, such as hydrogen, helium, lithium, and carbon, are often found in the earliest stages of the universe and are crucial for forming simple molecules and compounds. They play essential roles in various biological processes and are fundamental to the structure of matter.
How many electrons will group 2a lose?
Group 2A elements typically lose 2 electrons when forming ions.
What group of elements have a charge of 2 when forming ionic compounds?
Elements in Group 2 of the periodic table, such as calcium, magnesium, and strontium, typically have a charge of 2 when forming ionic compounds. This is because they readily lose two electrons to achieve a stable electron configuration.
Are molecules made up of atoms or combined elements?
Yes, atoms make up almost everything, they can only be broken down into protons, neutrons and electrons. An element is a substance found on the periodic table with certain rules and regulations given to each element. An element is made up only of atoms. A compound is a mixture of two or more elements that can be broken down into elements again, it is not a pure substance as such. So a compound is made up of elements, elements are made of atoms.
Which of these chemical elements is found in all organic molecules?
Carbon - Isaac =]
