What is s block |
| Answer» The\xa0s-block\xa0elements share electron configurations.\xa0s-block\xa0elements are the elements found in\xa0Group\xa01 and\xa0Group 2\xa0on the periodic table. ...\xa0Group 2\xa0is the alkali earth metals which have\xa0two\xa0valence electrons, filling\xa0their s\xa0sub level. Because they have\xa02\xa0valence electrons they are less reactive than\xa0group\xa01.The\xa0s-block elements\xa0include hydrogen (H), helium (He), lithium (Li), beryllium (Be), sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), rubidium (Rb), strontium (Sr), cesium (Cs), barium (Ba), francium (Fr) and radium (Ra). The periodic table shows exactly where these\xa0elements\xa0are within the\xa0s-block. | |
