Answer: a metal cation and the shared electrons that surround it

Explanation:

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals.In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions.

These de-localized electrons are the valence electrons of metal atoms which are shared between them.

A metal cation and a nonmetal anion are bonded by ionic bonding.

The answer is: a metal cation and the shared electrons that surround it.

Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Metallic radius is defined as one-half of the distance between the two adjacent metal ions.

Metallic bond increace electrical and thermal conductivity.

Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.

A balloon contains 11.1 g of nitrogen monoxide gas (NO). how many molecules are in the balloon?

grandymaker [24]

The number of molecules that are in balloon are = 2.227 x10^23 molecules

<h3> calculation</h3>

calculate the number of moles of NO

moles = mass/molar mass

molar mass of NO = 14+ 16 = 30 g/mol

moles is therefore= 11.1 g/30g/mol= 0.37 moles

by use of Avogadro's constant that is

1 mole= 6.02 x10^23 molecules

0.37 =? molecules

=(6.02 x10^23 x 0.37 moles)/ 1mole=2.227 x10^23 molecules

Select the correct answer. Based on the reactivities of the elements involved, which reaction will form products that are more s

FinnZ [79.3K]

Answer: The correct answer is option B.

Explanation: Reactivity of elements is defined as the tendency to loose or gain electrons.

These reactions are a type of single displacement reactions. A single displacement reaction is a type of reaction in which an element displaces another element in a chemical reaction. These are studied with the help of reactivity series.

The element which lies above in the reactivity series can easily displace the element which lies below in the reactivity series.

Option A: This reaction will not yield a stable product because Zinc lies below Aluminium in the reactivity series.

$AlBr_3+Zn\rightarrow \text{No reaction}$

Option B: This reaction will yield a stable product because Sodium lies above Calcium in the reactivity series.

$CaBr_2+2Na\rightarrow 2NaBr+Ca$

Option C: This reaction will not yield a stable product because Hydrogen lies below Magnesium in the reactivity series.

$MgBr_2+H_2\rightarrow \text{No reaction}$

Option D: This reaction will not yield a stable product because Calcium lies below Barium in the reactivity series.

$BaBr_2+Ca\rightarrow \text{No reaction}$

Option E: This reaction will not yield a stable product because barium lies below Lithium in the reactivity series.

$2LiBr+Ba\rightarrow \text{No reaction}$
