Answer:
e. Two different elements with a different number of electrons. Ions are atoms that tend to lose or gain electrons so as to gain a full outer shell.
Answer:
Explanation:
First, let's look at the Periodic Table.
We see that aluminum is a metal, while oxygen is a non-metal.
Now, let's recall three types of bonds
- Ionic: typically forms between a metal and a non-metal
- Covalent: usually forms between non-metals
- Metallic: tends to form with metals
Since we have a metal (Al) and a non-metal (O), aluminum oxide must have an <u>ionic bond.</u>
First of all, it is a nucleic acid, not nuclear acid.
Examples are DNA and RNA( Deoxyribonucleic Acid and Ribonucleic Acid)
Protons and Neutrons are the same size and have the same mass (1Amu)
If you notice, atomic mass is protons + Neutrons.
The mass of an electron is so small that it is often neglected in terms of calculations.
B electrons is the answer
