c CHARACTER INCREASES down the group, with tellurium CLASSIFIED as a metalloid and polonium as a metal. MELTING POINT, boiling point, density, atomic radius, and ionic radius all increase down the group. Ionization energy decreases down the group.

A.LAW of RECIPROCAL proportion The law of reciprocal proportions states that, "If two different elements combine separately with a fixed mass of a third element, the ratio of the masses in which they do so are either the same as or a simple multiple of the ratio of the masses in which they combine with each other".B.Law of constant proportion The law of constant proportions states that chemical COMPOUNDS are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.C.Gay Lussac’s Law Gay-Lussac's law (more correctly referred to as Amontons's law) states that the pressure of a GIVEN mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.D.Law of multiple proCompounds are made up of atoms of different elements. ... The law of multiple proportions, states that when two elements combine to form more than one compound, the mass of one element, which COMBINES with a fixed mass of the other element, will always be ratios of whole numbers.

6.022x10^23 X 1.5=9.033x10^23 MOLES x 7 ATOMS =6.3231x10^24 atoms. H2SO4 has 7 atoms.

first calculate the MOLES of  C O 2 = 100/44 = 2.27 mol now number of ELECTRONS in  C O 2 are obtained by ADDING TOTAL electrons in each of the three atoms i.e. two O and one C = 6+8+8 = 22 thus one mole of  C O 2 has  22 ⋅ 6.022 ⋅ 10 23 electrons and 2.27 mol has  2.27 ⋅ 22 ⋅ 6.022 ⋅ 10 23 electrons =  301.1 ⋅ 10 23 electronsExplanation:Mark me as a brainliest and follow me

Explain Group 17 elements.These five TOXIC, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (BR), iodine (I), and ASTATINE (At). ... Because the halogen elements have SEVEN valence electrons, they only require one additional electron to form a full octet.

The difference between the potential ENERGY of the actual structure and that of the contributing structure with the lowest potential energy is called the resonance energy or delocalization energy.
