How many protons, neutrons, and electrons does a neutral atom of this element have? (round atomic mass to nearest whole number)

Question 5 options:

A neutral atom of an element has the same number of __________ and ________.

Question 6 options:

Protons and electrons


Neutrons and electrons


Protons and neutrons


Which of the following is are isotopes of carbon? (Carbon has an atomic number of 6 and an atomic mass of 12)



Question 7 options:

Only B is an Isotope


A and C are Isotopes


A and B are Isotopes


B and C are Isotopes

Answer 1

Question 1 is The neutrally charged element in the nucleus of an atom = neutron

the number of protons an atom has = atomic number

an atom that has a different number of neutrons than the standard = isotope

protons + neutrons = Atomic mass

positive particle = proton

Question 2 don't understand what you're asking

Question 3 = Protons. If you add or remove a proton, it becomes a different element.

Question 4 = same as 3 "Protons"

Question 5 again don't understand what you're asking

Question 6 = Protons and Electrons. A proton is positive and an electron is negative, so together it balances out

Question 7 is there like a chart or something to go with it? if not then I'll just define isotope. An Isotope is basically atoms of the same element (so the number of protons can't change) and has a different number of neutrons so since neutrons have a prominent mass(or weight(sort of)) relative to electrons then the mass number will be different as opposed to the standard mass number of an element. For example Chlorine(Cl) has 17 protons and 17 neutrons but there are variants of it like Cl-35 which has 17 protons and 18 neutrons.

Simply put an Isotope has a different number of neutrons than protons

Answer 2

Answer:

given below.

Explanation:

1) a) the neutrally charged element in the nucleus of an atom --- Neutron

  b) the number of protons an atom has------------Atomic number

  c)  an atom of an element that has a different number of neutrons that the    standard atom of that element -----------isotopes

  d)  protons + neutrons in the nucleus of an atom  --------Atomic mass

  e) the positive particle in the nucleus of an atom----------Proton

2) correct answer is option d)

because  atomic number is less than atomic mass and atomic mass is nearly double to atomic mass so, best option leads to d.

3) correct answer is option d)

electron gives chemical properties to the atoms.

4) correct answer is option c)

proton is the element which give same number in all the atom.

5)  neutral atom is one which have same number of electron and proton so, best option comes out to be b) which is Aluminium.

6) neutral atom of element has same number of electron and proton.
