The strong nuclear force holds together which two particles in an atom? Electrons and neutrons Protons and electrons Neutrons and protons Neutrons and beta particles

Answers

Answer 1

Answer:

Answer:

Protons and neutrons

Explanation:

it confines quarks into hadron particles such as the proton and neutron. ... On a larger scale (about 1 to 3 fm), it is the force (carried by mesons) that binds protons and neutrons (nucleons) together to form the nucleus of an atom.

Answer 2

Answer:

Answer:

protons and neutrons

Explanation:

they are the two sides of the atom that are around the nucleus.

Which of the following is not a property of a base1. Has a bitter taste
2. Feels slippery to the touch
3. Reacts with active metals to produce hydrogen gas
4. Increases the concentration of hydroxide ions in an aqueous solution

Answers

Base has formula $Me(OH)_(x)$ .

Example of a base is a soap,

and it has a bitter taste, feels slippery to the touch.

From the formula we can see that a base has hydroxide ion (OH), so a base increases the concentration of hydroxide ions in an aqueous solution.

3. Reacts with active metals to produce hydrogen gas is not a property of the base; this is a property of acids.

A student hypothesizes that since elements in the same row have the same number of energy levels, they should behave the same in chemical reactions. Explain why you agree or disagree with this hypothesis.i'm having a bit of trouble with this question :P
anyone know?

Answers

Explanation:

When we move across a period then there occurs an increase in the number of electrons of atoms from left to right. These electrons are added to the same sub-shell.

For example, elements present in row 2 will have electrons present in n = 2 which is the highest energy level for row 2 elements.

Hence, there are different number of valence electrons present in the elements of a row.

Whereas when we move down a group then elements have same number of valence electrons. As a result, they tend to show similar chemical properties.

But since, there are no same number of valence electrons in the elements of a row. Hence, they do not show similar chemical properties. Therefore, elements of a row do not behave same in chemical reactions.

Thus, we can conclude that we disagree with the hypothesis given by the student.

I disagree with this hypothesis, because, the rows only support how many valence electrons there are, but do not support the chemical reaction. However, the columns do. Each column on the periodic table is one group. These groups share similar chemical properties, and react similarly in reaction. In conclusion, the hypothesis is incorrect.
Hope this helped.
