Answer:
It becomes negative
Explanation:
protons carry a positive charge
neutrons carry a neutral charge
electrons carry a negative charge
if we add 2 more electrons, the charge of the ion becomes negative

Actually Welcome to the concept of General organic chemistry.
1.) The formula for alkanes is Cn H2n+2
===> here n = 500, hence we get as,
C500, 2n+2 = 2(500)+2 ==> 1000+2 ==> 1002
hence the formula is ==> C500 H1002
2.) The formula for alkenes is,
CnH2n
hence, here n = 15
so we get as,
===> C15 H30
Answer:
The chemical equation can be written as:
2Mg+O
2
→2MgO
48 g of Mg reacts with 32 g of O
2
.
Thus, 4.8 g of Mg reacts with 3.2 g of O
2
.
Now, 32 g of O
2
forms = 80 g of MgO.
3.2 g of O
2
produces =
32
80
×3.2 = 8 g of MgO.

Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
