Question
about 96% of human body weight? h.2 Homework what four elements make up about 96% building blocks of elements are called ass of 207 and 125 neutrons in its nucleus, How many protons & 2 The electrons does it have& where are they located? 4. Three stable isotopes of oxygen are: 10 0 10. Oxygen has a standard atomic weight of 15.9994 and its atomic number is 8. Which isotope would you consider the most abundant? Identify the mass number, the number of protons, the number of electrons, and the number of neutrons for each isotope. 5. lonic bonds A. equally share electrons B. transfer electrons. C. unequally share electrons D. are more like attractions than true bonds. Most ionic compounds fall into what chemical category? 7. All ions are , substances that conduct an electrical current in solutionExplanation / Answer
1. C,H,O,N
2. Electrons, protons and neutrons
3. Protons are 82 and they are located in the nucleus.
Electrons are also 82 they are located in the orbits outside the nucleus
Mass no.- no. Of neutrons= no. Of protons
No. Of protons= no.of electrons
4. O 16
Mass no. = 16
Atomic no.= 8
No. Of protons= no. Of electrons= 8
No. Of neutrons= mass no.- no. Of proyons
= 16-8= 8
O 17
Mass no. = 17
Atomic no.= 8
No. Of protons= no. Of electrons= 8
No. Of neutrons= mass no.- no. Of proyons
= 17-8= 9
O 18
Mass no. = 18
Atomic no.= 8
No. Of protons= no. Of electrons= 8
No. Of neutrons= mass no.- no. Of proyons
= 18-8= 10
5. Ionic bonds transfer electrons
These bonds are formed by loss or gain of electrons.
6. Salts
7. Charged
