Answer:Atoms of nonmetals have a tendency to gain or share electrons when they react.
Explanation: Non-metals are elements that gain electron to form negatively charged ions known as anions.
When non-metals react, they either gain/accept electron from a metal atom or share electron with another non-metal atom. When a non-metal accepts an electron from a metal atom, the type of bond formed is called ionic or electrovalent bond. In electrovalent bond, the metal atom transfers its valence electrons to the non-metal atom so that both attain a stable octet or duplet structure.
When a non-metal shares electron with another non-metal atom, the type of bond formed is known as covalent bond. In covalent bond, the two non-metal atoms share a pair of electron, each atom donating one electron to form a pair.
Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Answer:
B
Explanation:
<em>Respiration </em><em>can </em><em>happen</em><em> </em><em>without</em><em> </em><em>sunlight</em><em>,</em><em>but </em><em>photosynthesis</em><em> </em><em>cannot</em><em>.</em><em>a</em><em>n</em><em>d</em><em> </em><em>photosynthesis</em><em> </em><em>doesn't</em><em> </em><em>take</em><em> </em><em>place </em><em>at </em><em>night</em><em>,</em><em>so </em><em>less </em><em>carbon dioxide</em><em> </em><em>is </em><em>used </em><em>up </em><em>than </em><em>it </em><em>is </em><em>produced</em><em>.</em>
