An acidic solution could have a pH of The three particles in an atom are 1.Protrons, neutrons, ions 2.Protons, neutrons, electrons 3.Proteins, lipids, carbohydrates 4.Isotopes, electrons, neutrons Which of the following is a positive test for starch? 1.Benedicts solution turns orange 2.Iod...
the smallest unit of an element that retains its distinctive properties what's the nucleus Made of closely bound protons and neutrons protons positively charged nuclear particles neutrons uncharged (neutral) nuclear particles electrons negatively charged particles surrounding the nucleus ...
number of protons, neutrons, and electrons in the neutral atom c. number of valence electrons d. tendency to gain or lose valence electrons e. charge on the ion Judging by its electron configuration and its location on the periodic table, how many valence electrons does chlor...
What is the number of electrons in each energy level for the element, H? What element gains three electrons to fill its valence energy level? How many protons does iodine have? What is plasma in nuclear chemistry? What element is a metal with 4 ele...

These elements in turn are composed of electrons, protons, and neutrons. These sub-atomic particles are composed of quarks, and the reductionist story may not even end there. The idea also breaks down when considered from a holistic (synthesis, frame up) view—are these elements sufficient to...
For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the...
All react with water to make strongly alkaline hydroxides. ( Alkaline hydroxides- class of chemical compounds which is made up of alkali metal cation and hydroxide anion.) The reactivity increases down the group. Atomic NumberElementNumber of electrons/outer shell 1Hydrogen1 3Lithium2,1 11Sodium2...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A number of radioactive isotopes of ...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
