Answer:
Choice B., infrared radiation
Explanation:
A gas in atmosphere which allows the incoming of the solar radiation to reach Earth's surface and on the other hand also absorbs these radiation which are re-emitted as heat, trapping heat in atmosphere and causing temperature to rise is called green house effect.
<u>For example, carbon dioxide is a greenhouse gas which traps heat from sun resulting in the warming the planet
.</u>
<u>Thus, infrared radiations which is a source of heat is reflected back to the Earth’s surface by greenhouse gases.</u>
Answer:
Wind
Explanation:
the other ones you can only use once
Answer:
Scandium, with atomic number of 21 = [Ar]3d¹4s²
Yttrium, with atomic number of 39 = [Kr]4d¹5s²
Lanthanum, with atomic number of 57 = [Xe]5d¹6s²
Actinium, with atomic number of 89 = [Rn]6d¹7s²
Explanation:
The electronic configuration of atoms of elements describes how electrons are arranged in the atomic orbitals of the atom. The electron configurations of atoms in standard notation is usually written sequentially with all electron-containing atomic subshells (s, p, d and f) and the number of electrons they contain in superscript. For example, the electron configuration of Neon is 1s²2s²2p⁶. However, an abbreviated notation can be used especially for elements having large atomic numbers. The symbol of the previous noble gas in square brackets indicating the core electrons is written before the outermost shell electrons of the atom. For example, the abbreviated electron configuration of sodium is [Ne]3s¹.
The electronic configuration of the given elements are shown below:
Scandium, with atomic number of 21 = [Ar]3d¹4s²
Yttrium, with atomic number of 39 = [Kr]4d¹5s²
Lanthanum, with atomic number of 57 = [Xe]5d¹6s²
Actinium, with atomic number of 89 = [Rn]6d¹7s²
