They have the same number of electrons in their outermost shell
Explanation:
Lithium, sodium, potassium, rubidium, cesium and francium are in the same column on the periodic table because they have the same number of electrons in their outermost shell.
- The periodic table is based on the precepts of the modern periodic law which states that "the properties of elements are a periodic function of their atomic number".
- In the table elements having the same number of electrons in the outermost shell of their atoms are placed over one another in vertical columns.
- Each of the resulting vertical column is known as a group or family.
- The given elements belongs to the first family on the periodic table.
- In this group, all the elements have just one electron in their outermost shell.

The energy of a photon of light is directly proportional to its frequency and <span>inversely</span> proportional to its wavelength.
Answer:
Explanation:
When he accelerates the heavy object up , the reading increases because an extra downward normal force acts on it, then scale reading returns to the same reading as when standing stationary, and then decreases as although he is lifting the heavy object , the acceleration is decreasing ,so the extra upward normal force acts.
