On a planet where the temperature is so high, the ground state of an electron in the hydrogen atom is n = 4. What is the ratio o
kvv77 [185]

Answer:

1:16

Explanation:

The ground state of an electron on the planet is n = 4 compared the ground state of an electron at n =1. For a hydrogen atom, the electron energy level is given as:

E(n)=\frac{13.6}{n^2}\\ \\Where\ n\ is\ the\ ionization \ energy

E(4)=\frac{13.6}{4^2}=\frac{13.6}{16}\\  \\E(1)=\frac{13.6}{1^2}=\frac{13.6}{1}\\  \\The\ ratio\ of\ their\ ionization\ energy=\frac{E(4)}{E(1)} =\frac{\frac{13.6}{16} }{\frac{13.6}{1} } =\frac{1}{16}=1:16

Hence the ratio of their ionization energies is 1:16

Write the answer in scientific notation when you multiply 2 x 104 by 3 x 104.
emmasim [6.3K]

Answer:

6× 10⁸

Explanation:

We need to find the multiplication of 2 x 10⁴ by 3 x 10⁴.

2 x 10⁴ × 3 x 10⁴

= (3 × 2) x 10⁴ x 10⁴

= 6 x 10⁴ x 10⁴

= 6 × 10⁴⁺⁴

= 6× 10⁸

Hence, the required answer is 6× 10⁸.

An atom has a nucleus that has mass and volume. How does the mass of the nucleus compare to the mass of the atom? How does the v
makvit [3.9K]

Answer:

The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.

The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.
