Protons and electrons are 12. For neutrons, there are 12 of them.
<span>Magnesium has an </span>atomic number<span> of 12, which means there are 12 protons.
You subtract the atomic number from the mass number in order to find neutrons.
</span>Atomic mass is 24. 24-12=12
Electrons always match the number of protons.
Answer:
2(a - 2b)
Step-by-step explanation:
2 is a common factor of 2a - 4b. The a's and b's cannot be part of the common factor.
2(a - 2b) is the answer.
Notice that both sides of the minus sign are effected by the two being taken out.
Answer:
1/13
Step-by-step explanation:
There are 4 sixes in a standard deck of 2 cards- six of diamonds, six of clubs, six of hearts, and six of spades. Drawing a 6 out of 52 cards would be 4/52 because there are 4 sixes ad a total of 52 cards. 4/52 can be simplified as 1/13 by dividing 4. 4/4=1 and 52/4=13. The probability of drawing a six out of cards is an 1/13.
Opposite sides are parallel.
Opposite sides are congruent.
Opposite angles are congruent.
Consecutive angles are supplementary.
The diagonals bisect each other.
Answer:
(6, 6)
Step-by-step explanation:
Point P is located at (6, -4). Point S is located 10 units above point P. This means we are going up on the y-axis. Going up 10 units from -4 puts point S at 6. Therefore, point S is located at (6, 6).
