Answer:
The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists, and other scientists. If you get to understand the periodic table and learn to use it, you'll be able to predict how chemicals will behave.
Answer:
c. a proton
Explanation:
A neutron is most equal in mass to a proton.
A neutron is a subatomic particle without any charges on them.
A proton is a subatomic particle with a positive charge.
- the mass of a proton and neutron are the most similar in an atom.
- the mass of a proton is 1.67 x 10⁻²⁷kg
- So also is the mass of a neutron
- the mass of an electron is 9.11 x 10⁻³¹kg
The type of bond that forms when two nonmetal atoms get close enough for their orbitals to overlap is called a covalent bond. Because both of these atoms are nonmetallic, neither atom has enough electronegativity to give up an electron to each other. What the atoms do, is the overlap their orbitals. The electrons in the shared orbitals can be considered to be in a covalent bond. They are held together by the attraction of both nuclei to the shared electrons.
