Electrons and protons are particles in an atom with equal but opposite charges. Electrons have a negative charge and protons have a positive charge. What is the charge amount of an atom with 2 more electrons than protons?

Step-by-step explanation:

- Protons are positively charged particles contained in the nucleus of the atom. They have a charge of

- Electrons are negatively charged particles orbiting around the nucleus of the atom. They have a charge of  

For a neutral atom, the number of protons is equal to the number of electrons, so the total charge of a neutral atom is:

In this problem, we have an atom having an excess of 2 electrons, i.e. it has 2 more electrons than protons.

Therefore, the charge of this atom will be:

and substittuing, we find

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
