A carbon atom has a strong tendency to do which of the following?. Answer. double bond with electrons. receive electrons. donate
Novay_Z [31]

Answer: Option (d) is the correct answer.

Explanation:

Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.

For example, C + 2H_{2} \rightarrow CH_{4}

A carbon atom is also able to form a double double with valence  electrons of other atom.

Thus, we can conclude that a carbon atom has a strong tendency to share electrons.

meriva

Answer:

Option B is correct. A nuclear alpha decay

Explanation:

Step 1

This equation is a nuclear reaction. So it can be an alpha decay or a beta decay

An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4.

During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2 less and a mass number 4 less.

Thus, radium-226 decays through α-particle emission to form radon-222 according to the equation that is showed.

A Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.

Option B is correct. A nuclear alpha decay
