What is the charge of an atom with 6 protons and 8 electrons?
A. +2
B. -2
C. +6
D. -6
Answer:
B
Explanation:
Because the electrons are greater than the protons which makes the atom negative charged.
And when you minus 6-8=-2
Hope this helped!
The charge of an atom with 6 protons and 8 electrons is -2. Because the number of electrons dominates by 2 units.
What is charge of an atom?Atoms in their neutral state have equal number of electrons and protons. Electrons are negatively charged particles and protons are positively charged particles.
Hence, all the positive charges are neutralized with equal number of negative charges. When atoms loss or gain electrons they gets charged and this charged atom is called ions.
When electrons dominates in number or atoms gain electrons they acquire negative charge and form anions. Similarly if atoms loss electrons they form positive ions.
Here, the number of electron is 2 greater than protons. Hence the charge of the atom is -2.

Calculate the molarity of a solution prepared by dissolving 13.0 g of Na2CrO4 in enough water to produce a solution with a volume of 800. mL .
Express the molarity to three significant digits.
Answer:
molar mass sodium chromate = 162g
12.6g ÷ 162g/mole = moles sodium chromate (This is the solute)
molalrity or M = moles solute ÷ lliters of solution (You'll have to change given mL to L)
