How many electrons are in the second energy level of an atom? What is an oxygen-18 atom? What is a helium-4 atom with no electron? How is the ionization energy of an element or atom calculated? The fifth row of the periodic table corresponds to what energy level in the a...
An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). What is the ratio of the number of electrons for each atom of lead over one atom of aluminum?
Electronic configuration is defined asthe distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number. Is the number of neutrons in oxygen 16? Therefore, oxygen 16 h...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
How many protons, neutrons, and electrons does silicon have? What is propane's density? A computer chip contains 1.20 \times 10^{23} atoms of silicon. What is its mass? What is the density of oxygen? What is the density of acetone?
The hydrogen ions and electrons then recombine on the cathode side of the fuel cell with oxygen molecules from the air, producing water vapor as a byproduct. The electricity generated by the fuel cell stack is then supplied to the electric motor, which powers the bus's wheels. Advantages of...
Oxidation and oxidisation refer to the same chemical process involving the loss of electrons; the difference lies in regional spelling preferences, with "oxidation" preferred in American English.
Nitrogen Uses and Properties - Nitrogen is a diatomic gas with atomic number 7 and symbol N. Know the nitrogen atomic number, the atomic mass of nitrogen and atomic weight of nitrogen. Explore the Uses of Nitrogen.
The same element can also vary in the number of electrons it has, creating ions. For example, sodium (Na) is a highly reactive element. Na can form an ionic bond with chlorine (Cl) where the sodium loses an electron -- becoming Na+ -- and gives it to the chlorine atom -- which ...
The atomic number of aluminum is 13. Thus, it contains 13 electrons. The distribution of electrons is as follows: 2, 8, 3. The total number...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
