When an atom that has no charge loses two electrons, it becomes a:
A: positive ion.
B: negative ion.
C: positive isotope.
D: negative isotope.

Answers

Answer 1

Answer: Option (a) is correct.

Explanation:

It is known that electrons hold a negative charge. So, when the negative charge that is electrons are taken out an atom then the number of electrons become less in number as compared to the number of protons.

Hence, the atom attains a positive charge.

An isotope is formed when an atom shows same number of protons and different number of neutrons. So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form.

Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.

Covalent compounds:
a)are formed from one metal and one nonmetal
b) exchange electrons in a chemical bond
c) have a low melting point
d)have weaker bonds than ionic compounds

Which answer would be correct i think maybe B

Answers

The Answer is D:

d) covalent bonds have weaker bonds than ionic compounds

The correct option is c i.e, have a low melting point. Covalent compounds have a low melting point due to weaker intermolecular forces. They are formed from two or more nonmetal elements and share electrons in a chemical bond.

Understanding the properties of covalent compounds is essential in Chemistry. Let's analyze each option provided:

Option A: Covalent compounds are not formed from one metal and one nonmetal. Instead, they are formed from two or more nonmetal elements.Option B: This option is incorrect because, in covalent bonds, atoms share electrons rather than exchange them.Option C: Covalent compounds indeed have a low melting point compared to ionic compounds. This is due to the weaker intermolecular forces present in covalent compounds.Option D: Correct. Covalent bonds generally have weaker bonds than ionic compounds, making it easier to melt or boil covalent compounds.

Given the above explanations, the correct answer is Option C: Covalent compounds have a low melting point.

A burning match would be an example of a chemical change: two or more reactants are altered into new substances. In  the case of a burning match, sulfur, wood, and oxygen are combining to made smoke and ash.

A burning match is an example of a chemical change. The transformation of two or more reactants into new compounds.

The term "chemical change" describes a process when one or more compounds are changed into new substances with new chemical properties. The atoms of the original substances rearrange themselves to establish new chemical bonds during a chemical transition, producing new molecules or compounds.

An illustration of a chemical change, in which two or more reactants are changed into new compounds, would be a burning match. Sulphur, wood, and oxygen combine to create smoke and ash when a match is lit.
