Identify the blocks and groups of elements in the periodic table​
djyliett [7]

Explanation:

The periodic table is a table that arranges elements based on their atomic numbers into groups and periods.

The groups are the vertical arrangement of elements. All elements in a group share similar chemical properties because they have the same number of elements in their valence shell. The periodic table groups are:

               Group                             Other names

              1A or 1                               Alkali metals

              IIA or 2                              Alkaline earth metals

             IIIA or 3                            Boron family

             VIA or 6                             Chalcogens

            VIIA or 17                            Halogens

             O-18                                  Inert elements

             IIIB-IIB                              Transition elements

There are 18 vertical columns divided into 8 tall groups or main groups which are 1A to O. The short groups or subgroups are from numerals 1B to VIII.

The periodic table can be divided into four blocks based on the type of sublevels their valence electrons occupy.

  • Group IA and IIA constitute the s-block
  • Group IIIA to O constitute the p-block
  • The transition elements makes up the d-block
  • The lanthanides and actinides makes up the f-block

Missions to mars are feasible only once every two years ?
krek1111 [17]

Answer:

Yes.

Explanation:

If you want to use the least fuel, then missions to Mars are feasible every two years.

You want to launch when Earth and Mars are close together, and this happens <em>about every 26 months</em>.

However, Earth travels faster than Mars, so the spaceship must launch when Mars is 44° <em>ahead </em>of Earth in its orbit.

The ship will then use the most efficient trajectory to arrive at Mars.
