  1. The element Sodium (Na) has a low electronegativity of the following elements.
  2. The element Beryllium (Be) has the least metallic character.
  3. The element Sodium (Na) has the largest atom.

<u>Explanation:</u>

  • Sodium (Na) which is a delicate, shimmering white, profoundly responsive soluble base metal loses an electron to a chlorine iota since it has seven electrons in its valence shell.
  • It needs one more electron to turn into a steady molecule. It has the most reduced electronegativity of the given components.
  • Beryllium (Be) is a light, silver-gray, relatively soft metal that is strong but brittle has the least metallic character of the given elements.
  • Since from left to right in a period, Metallic character decreases while nonmetallic character increases from top to bottom.
  • Sodium(Na) is the largest atom among the given elements since Atomic size decreases across a period from left to right and increases from top to bottom.

Forming a hypothesis is accomplished through _______ reasoning.
vfiekz [6]
Deductive reasoning involves making broad observations and examining possibilities to reach a specific, logical conclusion, which is required in the formation of a hypothesis. Conversely, inductive reasoning involves taking specific observations and making broad generalisations from these. Therefore the answer is A.

Hope this helps!

A charged object (like a balloon that's been rubbed on the wall) cant attract an object with a net neutral charge (neither posit
UNO [17]

Answer: A balloon is charged by a process of frictional charging and the object is getting charged by the process of induction.

Explanation:

When two bodies are rubbed against each other, charging by friction or rubbing occurs. The electropositive object loses electrons to electronegative object. Thus, when balloon is rubbed on a wall, it becomes charged.

The charged balloon is able to attract an uncharged object by inducing charge on it without the two objects touching each other. Electrostatic force acts between two charged objects. Charged balloon causes electrons to move at one end thereby inducing opposite charge in the object and thus, charged balloon is able to attract uncharged object.

In which conditions combination and displacement reaction takes place explain with example.​
expeople1 [14]
<h2>Answer:</h2>

In <u>Combination reaction</u>, two or more elements combined to form one compound of different properties.

  • C(s) + O2(g) ⇢ CO2(g).
  • H2(g) + O2(g) ⇢ H20(l).

In <u>Displacement reation</u>, the high reactive element displaces the low reactive element and formed compound of different properties.

  • Fe(s) + CuSo4(aq) ⇢ FeSo4(aq) + Cu(s).
  • AgNO3(aq) + Cu(s) ⇢ CuNO3(aq) + Ag(s).
