a) figure describe ionization energy , electron affinity & electron negativity
b) figure describe Atomic Radius
c) does represent anything
Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element. H-->Cl
Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy. M + IP-----> M+ + e-
Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.
X + e- ------> X- =- EA
Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
Answer:
We'll have 13.85 grams of potassium
Explanation:
Step 1: Data given
Moles KBr = 0.46 mol
Molar mass KBr = 119.00 g/mol
Molar mass K = 30.10 g/mol
Step 2: The balanced equation
2KBr ⇆ 2K + Br2
Step 3: Calculate moles of K
For 2 moles KBr consumed we'll have 2 moles K and 1 mol Br2
For 0.46 moles KBr we'll have 0.46 moles K
Step 4: Calculate mass of K
Mass K = moles K * molar mass K
Mass K = 0.46 moles * 30.10 g/mol
Mass K = 13.85 grams
We'll have 13.85 grams of potassium
Hey there!
Answer: Protons
The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well.
Thank you!
Answer:
Mass = 684.2 g
Explanation:
Given data:
Moles of Aluminium = 25.36 mol
Mass of Al = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Mass = number of moles × molar mass
Molar mass of Aluminium = 27 g/mol
Now we will put the values:
Mass = 25.36 mol × 26.98 g/mol
Mass = 684.2 g
