Elements with the same properties would be in the same group (Up and down row). Look at a periodic table and see which of the elements are in the same group. That will be your answer.<span />
Heat can be transferred from one material to another by direct touch (conduction), by differences in density of a fluid (temperature difference), and by RADIATION
Answer:
The molecular geometry of SO3 is trigonal planar.
Explanation:
Look at the Lewis
Answer: 45
Explanation:
Recall that mass number = number of protons + number of neutrons. Hence, the mass number of the atom
= 22 + 23
= 45
Furthermore, the atomic number is equal to the number of protons. Hence, since the number of protons is 22. the atom has an atomic number of 22
Thus, An atom that contains 22 protons,
23 neutrons, and 22 electrons would have a mass of approximately 45
