Connecting the Dots: Understanding the Theories and Theorists Directions: Refer to Chapter 1 in Developmental Profiles and to the lecture notes for more information on all the theories of child development. The points possible for each question are listed next to each question. (30 points total) 1. Name the four essential needs every child must have to thrive developmentally. Give an example of each need. (12 points) The four essential need that every child must have to thrive development

There is nothing that strikes fear into the hearts of trucking company owners and managers than an impending DOT audit. They’re nerve-wracking events‚ especially when you’re unprepared‚ but it doesn’t have to be that way. Trucking firms that hire DOT compliance companies are actually relaxed about audits. Why? Because they know that they have a reliable‚ experienced partner in their corner‚ that everything is documented properly‚ and that they’re in full compliance. Reliable‚ Experienced Partner

Compare and contrast the structure and bonding in Ionic‚ Covalent and Metallic species. Relate the structure and bonding to the properties of the species. Ionic bonding is usually formed between a metal and a non-metal‚ Covalent between two non-metals and Metallic between two metals. Ionic Bonding; Ionic bonds tend to form between metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred

Short Notes On Atomic Structure * Atom is the smallest particle of an element- All 117 elements has atoms * Bohr model: - Planetary model (see Figure 1 below) 1. Sun (proton & neutron= nucleus) 2. Planets (electrons) 3. Orbit (shell) Figure 1: Bohr model * Each type of atoms has a certain number of electrons and protons that differentiate it from the atoms of other elements Example: 1 proton 1 electron= Hydrogen (1 type elements) 2

4 = 6.9/ 7 * The atomic mass is the mean of all the isotopes of Lithium in nature; round the number * Isotopes of a specific element have a varying number of neutrons * The number of neutrons do not affect the chemistry because they are not electrically active; neutral * Mendeleev organized the elements according to their atomic mass but today we organized them according to their atomic number * Staircase line separates the metals from the non-metals

Electron domain can be described as a lone pair‚ single‚ double and triple bond‚ and also even free radical. Lone pairs tend to occupy a lot of space and lower the angle of a bond‚ which gives molecular geometry. Lewis structure help determine the molecular geometries‚ 3D structure‚ and distribution of electrons in order to understand the chemical properties of reactivity and molecules like texture and microstructure. One of the most important influences
