Fill in the blank: In ammonia, NH3, the total number of groups on the central atom is ___. Covalent Compounds Chemical compounds known as covalent compounds are created when atoms share electrons. These mixtures, which frequently contain nonmetals or metalloids, have low...
Ammonia molecule has the molecular formula NH3. In ammonia molecules, the central atom is Nitrogen that belongs to the VA group or 15th group or pnicogens or the Nitrogen family. Ammonia is a slightly basic compound, and Nitrogen is a non-metal. And, down the group, basicity increases. As...

Strontium is an alkaline earth metal. On the Periodic Table of Elements, strontium is given the symbol 'Sr' and the atomic number 38. Strontium is a solid at room temperature and has a melting point of 1431 degrees Fahrenheit.Answer and Explanation: ...
Is NH3 a base? How is water a molecule and a compound? Why are halogens diatomic? Why do ionic bonds form? Why do molecular compounds not conduct electricity? Why is NA3 not the correct formula for sodium nitrate? Why is IUPAC nomenclature important?
The formula for the ammonium ion is NH4+. The nitrogen atom is in the center and is single bonded to each hydrogen atom. The angle formed between the nitrogen-hydrogen bonds will be discussed. Related Chemical Terms Ammonium Ion: Ammonia, NH3, and ammonium are a ...
Which type of bond occur between bases in a DNA base-pair? a. covalent bonds b. ionic bonds c. hydrogen bonds Compare the degree of hydrogen bonding between the base pair A-T in DNA and the base pair A-U in RNA. What relationship exists between the atomi...
Ionic Compounds: The chemical formula of an ionic compound reflects a charge-neutral compound with the simplest ratio of cations and anions present. The sum of the positive charges is equal to the negative charges. In this way, the empirical formula of an ionic compound is equ...
