3. Explain why the statement "electrons are always located close to the nucleus of an atom" is not really accurate,

Answers

Answer:

Electrons are stored in different electron shells with the nucleus in the center. Depending on the size of the element, the electrons may need more shells, making the electrons further away from the nucleus.

Explanation:

Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.  the statement "electrons are always located close to the nucleus of an atom" is not really accurate.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge.

Electrons always move in fixed orbit around the nucleus with a particular force. Electrons may or may not be close to the nucleus. Depending on the size of the element, the electrons may need more shells, making the electrons further away from the nucleus.

Therefore,  the statement "electrons are always located close to the nucleus of an atom" is not really accurate.

What should the IUPAC name for a binary covalent compound lack? prefixes Roman numerals an -ide ending the name of a nonmetal.

Answers

The IUPAC name for a binary covalent compound will lack roman numerals.

Binary covalent compound comprises of two elements which forms a

compound through the sharing of electrons.

The sharing of electrons is referred to as covalent bonding and naming such

compounds require prefixes such as mono-, di- , tri- etc.

The standard method of naming these compounds should be with the

prefixes and not with the roman numerals.

An example is carbon(IV)oxide which is wrong in  IUPAC naming.

why does fluorine have the highest electronegativity

Answers

Answer:

Because it only needs one more electron to get to a full valence shell (8), so it really wants it and is pulling other electrons in. It also has to do with needing one more electron to fill the 2p shell. It is a small element which means its electrons are pulled tightly to the nucleus.

Which neutral atom is isoelectronic with N-3?

Answers

The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Isoelectronic are those which have same number of electrons or we can say that same electronic structure.

For finding out that the species are isoelectronic , we just have to count there no. of electrons of atoms and if they have same no. of electron then they said to be isoelectronic species.

no. of electrons in Nitrogen N = 7 ( atomic no.)

no. of electrons in Nitride ion N⁻³ = 7 + 3 = 10

no. of electrons in Neon Ne = 10 ( atomic no. and neutral atom)

so, no. of electrons in Nitride ion N⁻³  = no. of electron in Neon Ne

this means , N⁻³ , Nitride ion is isoelectronic with Neon Ne.

Thus, The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Rebekah finds that a solution of sugar in water has a volume of 1. 32 fl. Oz. How should she report this amount using the metric system? (1 fl. Oz. = 29. 6 mL) 0. 403 m 1. 40 qt 37. 5 g 39. 1 mL.

Answers

Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.

The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.

The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.

Thus, the volume of sugar solution has been reported in mL.

The given sugar solution has volume of 1.32 fl. Oz

The volume in mL can be given as:

[tex]\rm 1\;fl\;Oz=29.6\;mL\\1.32\;fl\;Oz=1.32\;\times\;29.6\;mL\\1.32\;fl\;Oz=39.1\;mL[/tex]

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.

how do i find the number if electrons in an element​

Answers

Answer:

by using this formula 2×(n)^२

Answer:

M-A=N

Explanation:

M-A=N

Here is an example.

The equation above means that the atomic number (A) subtracted from the average atomic mass (M) equals the combined amount of neutrons and protons. Since we know that 35 17Cl is Chlorine (this is because Chlorine (Cl) is the 17th number on the periodic table and has the average atomic mass of 35), we can insert our data into the equation and end up with the following:

35-17=18.

From here, we can tell that we have a mix of neutrons and protons, with the total being 18. Since the atomic number is 17, we can reasonably assume that there are 17 protons and 1 neutron.

But we still need to find the number of electrons. Fortunately, the number of electrons is always equivilant to the number of protons and the atomic mass, so we know that the number of electrons is 17.

So, we have;

17 Protons

1 Neutron

17 Electrons
