Answer 1

you need to add FormsModule to the a atendimento.module.ts as well, since your component is a part of AtendimentoModule

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';

import { AtendimentoRoutingModule } from './atendimento-routing.module';
import { AtendimentoComponent } from './atendimento/atendimento.component';
import { FormsModule }   from '@angular/forms';
@NgModule({
  imports: [
    CommonModule,
    AtendimentoRoutingModule,
    FormsModule 
  ],
  declarations: [AtendimentoComponent]
})
export class AtendimentoModule { }
