Answer:
Element Lithium
Explanation:
The element with the highest second ionization energy is lithium. It belongs to the alkaline metal group I.e group one metals
It has the highest second ionization energy because it is very difficult to remove the electron from the 1s orbital.
Its atomic number is 3. The electronic configuration is 1s2 2S1
In 1954 at 5:29am in New Mexico.
Each alka-seltzer tablet contains 324 mg of aspirin. Three alka-seltzer tablet contains (3 x 324)mg= 972 mg of aspirin= 0.972 g of aspirin.
Molecular formula of aspirin is C₉H₈O₄. Molar mass of aspirin is (9 x 12)+(8 x 1)+(4 x 16) g/ mol= 180 g/mol.
180 g of aspirin contains 1 mole of aspirin molecules i.e, 6.023 X 10²³ number of aspirin molecules. So, three alka-seltzer tablet that is 0.972 g of aspirin contains (0.972 X 6.023 X 10²³)/180 =3.25 X 10²¹ number of aspirin molecules.
Neutron = No charge / Mass of 1
Proton = Postive charge Mass of 1
Electron = Negative charge No mass
