a.
To draw: An electron distribution diagram for hydrogen, 1H.
Introduction: The basic unit of matter that has the properties of a chemical element is called an atom. Atom is made up of subatomic particles (neutrons, protons, and electrons). The substance that is made from one type of atom is known as an element.
b.
To draw: An electron distribution diagram for carbon, 6C.
Introduction: Every element has smallest unit of matter that retains the properties of an element”. This smallest unit is called atom. There are three subatomic particles of an atom. These are electrons, protons, and neutrons.
c.
To draw: An electron distribution diagram for oxygen, 8O.
Introduction: In the simplest level of organization, human body consists of various chemical structures. These chemical structures include atoms, ions, and molecules. The atoms and molecules are made up of matter.
d.
To draw: An electron distribution diagram for sodium, 11Na.
Introduction: The basic unit of a matter which possesses the properties of a chemical element is defined as an atom. An atom is made up of nucleus in the center and one or more electrons surround the atomic nucleus.

How many grams of oxygen are needed to react with 8.5 L of acetylene gas at STP? d. How many liters of CO2 gas at STP are produced when 30.0 g of acetylene undergoes combustion?arrow_forward
- Considerthese following ions: 02 -, N -, Li2 + and O - a. Based on molecular orbital theory (MOT), which of the ion(s) exhibit(s) paramagnetism? b. For those ions that are paramagnetic, determine the number of unpaired electrons. Support your answers with draw appropriate molecular orbital energy diagram.arrow_forwardThe elements oxygen and sulfur have similar chemical properties because they both have six electrons in their outermost electron shells. Indeed, both elements form molecules with two hydrogen atoms, water (H2O) and hydrogen sulfide (H2S). Surprisingly, at room temperature, water is a liquid, yet H2S is a gas, despite sulfur being much larger and heavier than oxygen. Explain why this might be the case.arrow_forwardCompound A has molecular formula C7H7X. Its 1H-NMR spectrum shows a singlet at 2.25 ppm and two doublets, one at 7.28 ppm and one at 7.39 ppm. The singlet has an integral of three and the doublets each have an integral of two. The mass spectrum of A shows a peak at m/z = 126 and another peak at m/z = 128; the relative height of the two peaks is 3:1 respectively.
