How did the First Great Awakening affect attitudes toward religion in the colonies during the early 1700s?</span>
A is correct. If an atom has more protons than electrons it is positively charged, if more electrons than protons it is negatively charged. An equal number of each will make it neutral
Basically they are asking you to find the element that is most closely associated with these clues.
1. Fireworkium: 15 protons and 15 electrons? No problem. We can see that the atomic number is 15, in which in real life, the element is Phosphorous. (Phosphorous is a common element in fireworks for an explosive personality and colors)
2. Toothium: A nonmetal with average mass number close to 19? We check the periodic table once more and find that Fluorine is our answer. (Notice that fluorine is in toothpaste, which is why they decided the name Toothier)
3. Breathium: Now honestly, I didn't even have to check the periodic table but just realize that we breath Oxygen. But if you want the straight answer, Oxygen is a nonmetal which has an atomic mass close to 16, and surprise, it has one less proton than Fluorine.
4.Lightium: Immediately we see that since this gas does not react with other elements, it is a noble gas. If it glows in a lamp or vacuum tube, we can also see it is of a light origin. If it has one more proton than Toothium (Fluorine) than we can immediately see that in the periodic table, our answer is Neon.
5. Rottoneggium: We can immediately guess sulfur. The straight way shows that it has 16 electrons, and the non-ion atom should also have 16 protons. Therefore, our answer is Sulfur.
6. I just realized I forgot Floatium: If it has 2 protons, we look in the periodic table and see that our answer is Helium.
In chemistry, "chemical properties" of elements usually refers to the electron affinity of an atom (number of valence electrons) This is because atoms with the same number of valence electrons will form similar compounds with other atoms, and undergo the same types of reactions.
Out of this list: He, Ne and Ar are all group 18 elements (Noble gases)
Therefore they have similar chemical properties.
The given blank can be filled with endothermic reactions.
The endothermic reactions or processes captivates energy from its surroundings, primarily, but will not always be in the form of heat. A reaction, which requires the input of energy that dissociates a bond will always be endothermic. The best examples of endothermic reactions are evaporation of the liquid, melting cubes, melting or solid salts, and others.
