1. Which of the following statements about the properties of elements related to an
Thepotemich [5.8K]

The emission spectrum of an atom consists of limited lines that are unique to a given element.

According to the Bohr model of the atom, energy is absorbed or emitted when an atom moves from one energy level to another. Since energy is quantized, the spectrum of atoms often consists of single lines.

Hence, the true statement about atomic spectrum is that; "the light that an element emits is made up of a limited number of narrow lines that produce a unique pattern or atomic emissions spectrum for that element."

How many single covalent bonds could an element with the electron
Tcecarenko [31]

Answer:

1

Explanation:

I would say 1 because that configuration has 7 valence electrons.  The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet.  To get the one electron to fill the valence shell it would only need to have 1 covalent bond.

I hope this helps.  Let me know if anything is unclear.

Carbon-14 has a half-life of 5,700 years.
Maksim231197 [3]

Answer:

3.106\ \text{g}

Explanation:

t_{1/2} = Half-life of carbon = 5700 years

t = Time at which the remaining mass is to be found = 10400 years

m_0 = Initial mass of carbon = 11 g

Decay constant is given by

\lambda=\dfrac{\ln2}{t_{1/2}}

Amount of mass remaining is given by

m=m_0e^{-\lambda t}\\\Rightarrow m=m_0e^{-\dfrac{\ln2}{t_{1/2}} t}\\\Rightarrow m=11e^{-\dfrac{\ln 2}{5700}\times 10400}\\\Rightarrow m=3.106\ \text{g}

The amount of the substance that remains after 10400 years is 3.106\ \text{g}.
