It is Titanium (II) Phosphate.
Answer:
positively charged nucleons are 24
Explanation:
Given element:
₂₄⁵⁰ Cr
The superscript before the symbol of the atoms is mass number
The subscript before the symbol is the atomic number
Cr is the symbol of the atom
Now,
Atomic number is the number of protons in an atom.
The protons are the positively charged particles in an atom.
For this specie, the positively charged nucleons are 24
Answer:
0.43×10²³ atoms
Explanation:
Given data:
Mass of LiBrO₂ = 4.28 g
Number of atoms of oxygen = ?
Solution:
Number of moles = mass/molar mass
Number of moles = 4.28 g/ 118.84 g/mol
Number of moles = 0.036 mol
We can see 1 mole of LiBrO₂ contain 2 mole of oxygen atm.
0.036 mol × 2 = 0.072 mol
1 mole contain 6.022×10²³ atoms
0.072 mol × 6.022×10²³ atoms / 1mol
0.43×10²³ atoms
Answer:
To find the noble gas notation, you first take the noble gas before the element you’re trying to find the notation for. In this case, the noble gas before Calcium is Argon. You put the symbol for Argon in square brackets, and then you write out the rest of the notation as you would normally.
This would look like [Ar]4s^2
The 4s^2 is because Calcium is the second element in the 4s columns (refer to the diagram)
Hope this helps :)
