The last one would be false
Periodic table is arranged and organized with special pattern or regular variation of the properties of an element with increasing atomic number, this is called periodic trend. So periodic trend look like a repeating pattern on the periodic table.
Some of the trends are density, atomic radius,melting point, boiling point, electronegativity etc.
A molecule is a neutrally charged group of atoms held together by one or more COVALENT bonds
The following are the answers:
=oxygen equals to a charge of 2-
number of atoms is -24
=Mn equals to the charge of +3
Mn= 3+3x-24=0
let x be the charge of Cl, so:
23-3=3x
20/3=x
=6.67 or 7
x= 7
= Cl has a charge of +7
You are right about your answers
