The Chlorine and fluorine atoms are the most electronegative.
So, option D and E is correct one.
The atom of a given chemical elements having tendency to attract bonded pair of electron toward itself is called electronegativity. The electronegativity of atoms is affected by both its atomic number and distance at which its valence electrons resides from the charged nucleus.
The electronegativity of the elements is increases on moving left to right in the period of periodic table while decreasing on moving top to bottom in the group of periodic table .
Example:
The elctronegativity of fluorine atom = 3.98
The elctronegativity of chlorine atom =3.16
The elctronegativity of carbon atom = 2.25
The elctronegativity of phosphorus atom = 2.19
The elctronegativity of silicon atom = 2.58

Answer:
5SiO2 + 2CaC2 → 5Si + 2CaO + 4CO2
Explanation:
When you are balancing an equation, you use coefficients to change the number of atoms of each type that are on each side of the equation.
You cannot change subscripts, the small numbers to the right of the substances. You can only add coefficients, the large numbers to the left of substances.
A balanced equation has the same number and type of atoms on both sides of the equation (the reactants on the left, the products on the right).
To begin, this equation has:
1 Si
2 O
1 Ca
2 C
on the left and
1 Si
1 Ca
3 O
1 C
on the right. Those numbers don't match!
By adding coefficients we end up with 5 Si, 10 O, 2 Ca and 4 C on both sides.
I don't want to go anywhere apart from <u>than</u> Nairobi.
A. instead
B. only
C. besides
<h3>D. than</h3>
